17 Best Hiking Sleeping Bags In Australia For 2024

Imagine snuggling into the best hiking sleeping bag at the edge of your tent as you watch the sky turn a million shades of pinks and purples, the final light of the sun casting glowing beams across the mountainous valley beyond. 

There is no better feeling than making it to camp after a long day on your feet and jumping into your sleeping bag, ready to watch nature’s best show. Perhaps the only thing that could possibly be better is your unwavering trust that your hiking sleeping bag will keep you warm and cosy even when the overnight temperatures plummet. 

Finding the best sleeping bag for hiking can be a real pain, not to mention a super uncomfortable trial and error process – trust me, I’ve been there many times! But once you find a sleeping bag that doesn’t weigh a ton and can keep you warm in the coldest conditions, all that searching proves its worth. 

I have tested many hiking sleeping bags in my time and unfortunately, spent many nights convinced the shivers would never stop. So to avoid others having to go through this frustration, we have put together the ultimate guide to choosing the best hiking sleeping bag in Australia!

How To Choose The Best Hiking Sleeping Bag

Understand The Climate You Predominately Hike In

The first thing to consider when buying a new hiking sleeping bag is where you predominantly plan to camp. More specifically, how cold does it typically get and what is the average rainfall for your intended destinations?

While temperature is an obvious factor, rainfall might surprise you. However, hiking sleeping bags aren’t waterproof (more on that below) and if you know the insides of your tent are often going to be damp, you may want to look for a sleeping bag with some water-resisting properties. 

If you’re new to camping in the mountains, you may not know the answers to these questions. However, you can get a good understanding using the resources below:

  • Research the climate history of your desired destinations on BOM or equivalent
  • Use Mountain Forecast to look up your bucket list hikes and check the temperatures at the summit (don’t forget to look at the wind-chill temp)
  • Ask a friend or post your questions in a Facebook group related to hiking in your chosen destination

Pro tip: Think hard about where you expect your hiking adventures will take you. Sleeping bags for hiking aren’t cheap and if you know you want to progress to bigger hikes in wilder terrain, get a sleeping bag that will suit those expeditions. After all, you can always unzip the bag when you get too hot! 

Quick Buyers Guide For Hiking Sleeping Bags

  • Use the comfort rating on the sleeping bag as your limit, even if you’re male
  • Choose a sleeping bag with a comfort rating at least 5℃ colder than you expect to camp in
  • If you regularly camp in wet climates, look for a synthetic option or a down sleeping bag that uses hydrophobic down
  • The higher the denier count, the more durable the sleeping bag will be
  • A higher loft count for a down sleeping bag will result in a lighter and more compressible option
  • If you’re a woman and feel the cold, purchase a women’s specific sleeping bag. They often have a little extra insulation around targeted areas

Sleeping Bag Warmth

As you may have guessed, the most important aspect of a sleeping bag is its warmth. And luckily, there are standards in place to test sleeping bags equally so that you can compare brands with confidence. 

These standards are called the EN-13537 and ISO-23537 and are both so similar (ISO being the newest organisation) that we can regard them as one and the same. The most recent standard I can find is ISO-23537-1:2022.

The majority of sleeping bag brands will test their sleeping bags through one of these organisations, but it’s not mandatory. However, each sleeping bag on our list below uses these standards. 

Temperature ratings

The EN and ISO tests both involve a heat-monitored manikin dressed in base layers and a beanie, lying inside the sleeping bag in question on top of an insulated sleeping mat. The room is climate controlled to produce the desired temperatures. 

The tests produce three outcomes that are included in the temperature rating, these are:

  • Comfort Rating: The temperature at which a woman or cold sleeper can comfortably sleep through the night
  • Lower Limit Rating: The temperature at which a male or warmer sleeper can comfortably sleep through the night
  • Extreme Limit: The temperature at which a woman or cold sleeper can withstand for 6 hours without risk of death

It’s important to note that these ratings are done in a regulated room and therefore cannot account for uncontrolled factors such as the quality of your sleeping mat and base layers or the fit of your sleeping bag for your body size. 

To give yourself a buffer and accommodate for any uncontrolled factors that may arise, we suggest choosing a sleeping bag with a comfort rating of at least 5℃ colder than you expect to camp in.

We also suggest basing your decision on the comfort rating no matter if you’re a warm or cold sleeper – after all, if you get too hot you can just unzip your sleeping bag but there’s nothing worse than shivering your way through a frosty night!

Pro Tip: A great way to add extra warmth to your hiking setup is to pair your sleeping bag with the best sleeping mat and a sleeping bag liner.

Sleeping Bag Shape

I briefly touched on the subject of a sleeping bag’s fit above which is ultimately a result of the shape you choose to buy. A sleeping bag’s shape is an important factor because it affects the overall warmth as well as the weight. 

Your sleeping bag works by maintaining the warmth of your body. But if there is a lot of excess space inside your sleeping bag, it has to work harder to warm up that extra space as well. This is why most people who want the warmest sleeping bag for hiking will choose one that fits snug. 

However, if you choose a snug-fitting sleeping bag then you will sacrifice the ability to move around freely. Some will find this severely uncomfortable and therefore may want to sacrifice the extra warmth and lowered weight for comfort. 

There are three main sleeping bag shapes that you can choose from which are: 

  • Mummy-shaped sleeping bag: The warmest and lightest option, this sleeping bag will snuggly fit the contours of your body and taper off around the feet. This allows for the elimination of excess space and shaves off unnecessary weight
  • Relaxed tapered/tapered rectangle sleeping bag: This sleeping bag will taper at the feet to eliminate some weight and space but not quite as much as the mummy, allowing for more movement
  • Rectangular sleeping bag: This is the coolest and heaviest shape but, as a result, offers extra room to move

Women’s Specific Sleeping Bags

Packing down camp while stuffing sleeping bags in to rough sacks

Statistically, women sleep colder than men and are generally a different shape. This is why you’ll often be faced with a women’s option or equivalent for most backpacking sleeping bags. These styles generally offer more insulation and warmth compared to the men’s equivalent, plus a slightly altered shape to suit that of the average female.

While this won’t benefit all women, for those that do sleep cold, I highly recommend purchasing a women’s specific sleeping bag.  

Key Differences in a women’s and men’s sleeping bag:

  • Shorter length: Women’s sleeping bags are generally designed to fit heights up to 5”6 while men’s are designed for heights up to 6”
  • Altered shape: A women’s sleeping bag will have more room in the hips and narrower shoulders, while a men’s sleeping bag will have wider shoulders and a straighter cut
  • Extra insulation: In a woman’s sleeping bag, you’ll find more insulation (and as a result, a heavier weight) compared to the men’s equivalent

Hiking Sleeping Quilts / Blankets

Along with a traditional sleeping bag, you also have the option to purchase a quilt. A sleeping quilt saves weight with the elimination of a zipper and the use of less material and allows unrestricted movement. 

A sleeping quilt often comes with straps to secure the quilt around your sleeping mat and a cinch cord at the footbox to keep your feet warm. While a quilt won’t offer nearly as much warmth as a sleeping bag, it is a popular choice for ultralight hikers during summer.

Sleeping Bag Insulation

Sleeping bag Insulation refers to the stuffing that’s inside the bag and is generally constructed with down (duck or goose feathers) or synthetic fibres. Much the same as with Down Jackets, both insulators have their positives and negatives. 

Down Sleeping Bags

Down sleeping bags, like down jackets, have an exceptional weight-to-warmth ratio that synthetic sleeping bags just can’t compete with, yet. But even within the range of down sleeping bags, you will come across varied quality and weight. So before we move on, let’s get a little background knowledge on down.

Firstly, what is down?

Down comes from birds and is the layer of fine feather or plumage found under the tougher feathers at the underbelly. The down we collect for jackets, pillows, sleeping bags and such are generally from ducks or geese.

The plumage of ducks and geese provides incredible insulation due to the high-loft (fluffy) clusters creating thousands of air pockets that trap body heat and air. Down not only retains heat, but it’s also super breathable which allows it to wick moisture away from your body. 

The warmth of a down sleeping bag comes down to three factors:

  • Duck or goose down: Because geese are larger animals, their down clusters are bigger and stronger. This makes for a warmer sleeping bag if all other aspects are the same. However, duck down shouldn’t be completely disregarded. It is cheaper due to more availability and fares better when wet.
  • Down fill power: The fill power for a down sleeping bag measures how much loft the down clusters have. For example, for a fill power rating of 850, one ounce of down can cover 850 cubic inches. Basically, the higher the fill power, the better quality the down and the better the warmth-to-weight ratio. 
  • Down fill weight: Fill weight is all to do with quantity. If a sleeping bag has a fill weight of 400g, then 400g of down material was used to insulate the sleeping bag (more on this below).

Synthetic Sleeping Bags

Synthetic sleeping bags lack in the warmth-to-weight ratio in comparison to down sleeping bags, however, they do excel in other important areas. 

Firstly, synthetic sleeping bags outrank down sleeping bags in their performance when wet. While down loses most of its insulating properties when wet, synthetic sleeping bags will continue to keep you warm. 

Secondly, you’ll often find a cheaper price tag on a synthetic sleeping bag as opposed to a down. So if weight isn’t the driving factor in your decision, a synthetic option might be best for you. 

The material used for synthetic insulation in a hiking sleeping bag is usually polyester or Primaloft. This is often a great sustainable option as you can easily find a brand that uses recycled fabrics. 

Sleeping Bag Fill Weight

I touched on fill weight in regards to down, however, it also relates to synthetic sleeping bags and there is a little more to it. 

As I stated above, the fill weight relates to how much insulation is packed into a sleeping bag and a higher fill weight will loosely relate to a warmer sleeping bag. However, to have a good warmth-to-weight ratio, this has to be matched with a high loft count or premium synthetic material. 

For example, a sleeping bag with a fill power of 800 and a fill weight of 690g is warmer than one with a fill power of 850 and a fill weight of 485g. However, the latter sleeping bag will be much lighter and pack down smaller. 

Weight Of A Hiking Sleeping Bag

When you’re carrying everything you need for a few days on your back, every gram counts! But the lightest sleeping bag will often come at a sacrifice of warmth, durability, or your life savings.

If weight is your second biggest priority (warmth should always be the first) then there are a few components you can familiarise yourself with to find the best lightweight sleeping bag. 

  • Down is lighter than synthetic: For synthetic to reach the same warmth rating as down, it tends to be considerably heavier
  • Down fill power: The higher the loft count, the lighter the sleeping bag
  • Half-zips or no zips: To eliminate some weight, you can find lightweight sleeping bags with either no zips or only a half zip, but this does affect temperature regulation
  • Mummy-shaped sleeping bags: This shape cuts away excess material for a snug fit, saving weight in the process
  • Lower denier for the outer shell: The lower the denier, the lighter the bag will be – although this does impede durability

Pro tip: Choose the warmth rating you need for you and your intended destination before considering the weight. Once that’s decided, you can search for the lightest option in that warmth range. 

Packability

Packability of a down insulated sleeping bag

The packability of a sleeping bag refers to the size it can compress to. You can find this measurement listed as the compressed volume and it will coincide closely with the fill weight of a sleeping bag. 

The higher the fill weight needed, the less the sleeping bag will be able to compress. There are a few other factors that also contribute to the overall compression size of the sleeping bag such as the zipper, waterproofing, denier count and extra features. 

The compressed size of a sleeping bag is important if you only have a small backpack or little room to spare. This is where choosing a higher loft will benefit as less fill weight is needed to provide the same warmth.

Water Resistance

A sleeping bag is not waterproof by any means, but some elements can aid in keeping the bag a little more resistant to the dampness that often lingers inside your tent. 

  • Synthetic sleeping bags: This is an area where synthetic sleeping bags outshine down sleeping bags. When down gets wet it clumps which affects its insulating capabilities considerably. However, when synthetic fibres get wet, they perform better than down. 
  • Hydrophobic down: In recent years, a technology has been created called hydrophobic down. This is a polymer coating on the feathers that protects them from moisture and avoids clumping. As with everything, you’ll find both good and bad reviews on hydrophobic down. Some say that all it does is add false fill weight to the bag (it makes the feathers heavier but doesn’t actually increase warmth), while others swear by it and don’t mind the extra weight in exchange.
  • Water resistant outer fabrics: Most sleeping bags will have a DWR coating or similar, or an outer fabric called Pertex Quantum which is a type of nylon ripstop with water resisting properties.
  • Durable and water-resistant footbox: Some sleeping bags have a tougher nylon material for the footbox of the sleeping bag, which also adds extra water resistance as it’s a tougher barrier for the water to seep through. This helps to stop your feet from getting wet when they inevitably brush up against the side of the tent. 

If you live in a wet climate and find yourself staring at a drip inside your tent on a regular basis, then the water resistance of your sleeping bag is an important aspect to factor in. 

Durability Of A Backpacking Sleeping Bag

A hiking sleeping bag’s durability is measured by the outer shell fabric. The fabric is made of nylon, polyester, or a combination of both. Common words you’ll come across in regards to the shell fabric are:

  • Ripstop: A fabric (usually nylon) that is woven in such a way that reinforces it, making it more resistant to tearing and ripping
  • Pertex: Similar to GoreTex, this is a brand of lightweight, synthetic fabrics that have been designed to protect against the weather while still offering superior breathability and comfort
  • Taffeta: A plain-woven fabric that offers a little more quality and comfort than ripstop, usually used in the lining of a sleeping bag
  • Denier (D): Refers to the sleeping bag outer shell’s density. Basically, the higher the number, the thicker the fabric and subsequently, the stronger the sleeping bag will be

The durability of a sleeping bag is not often the highest priority because its primary purpose is for sleeping inside a tent. However, I find myself wrapping my sleeping bag around me (or jumping into it) while outside or walking around an alpine hut more often than I expected. 

Had I known this before purchasing my hiking sleeping bag, I would have taken more consideration of the denier count (thickness of the nylon outer) and looked for one with an extra durable footbox.

Denier is the most important component when you’re searching for a durable hiking sleeping bag. Lightweight sleeping bags often sacrifice durability for weight and are therefore the least durable. The denier count is often between 10D and 30D, sometimes with 50-70D on the footbox. If durability is more important than shedding a few grams then look for a sleeping bag with at least a 30D outer shell. 

Features

You may not think there could be much difference between hiking sleeping bags when it comes to features but you’d be surprised! While they’re all made relatively similar, some stand-out features allow for an extra comfortable or warm sleep.

Draft Collars And Tubes

A draft collar is an extra line of insulation around your neck to prevent warmth from slipping past. Similarly, a draft tube runs along the inside of the zipper to prevent any warmth from escaping. 

Sleeping Bag Hoods

Most hiking sleeping bags will come with a hood to add extra warmth and the ability to cinch it snugly around your entire body using drawcords. This is a feature I would not sacrifice.

Stash Pockets

This handy little feature is often just a small zippered pocket inside your sleeping bag where you can stash things like your lip balm or some earplugs. It is often large enough for your phone but I find that to be rather uncomfortable as the pocket is usually located on your chest and something heavy will weigh it down. 

Water-resistant Footbox

Some hiking sleeping bags will have a thicker denier material covering the footbox. This can help prevent ripping if used outside and aids in avoiding the moisture from your tent walls to seep through. 

Sleeping Bag Zippers

Most zippers that you will find on sleeping bags for hiking will have an anti-snag feature. An anti-snag zip can either be created using a guard along its length or a cover for the zip. This is highly important because most of the rips will occur here, resulting in a loss of insulation. 

Not all zippers will run all the way to the footbox. To save weight and add extra warmth, some will be either half zips or maybe there will be no zip at all. The only downside is that this lowers your temperature regulation abilities.

Some brands also provide zips on different sides to allow for their bags to be zipped together to create a double sleeping bag for you and your partner. 

Sustainability

Finding a sustainable option for a hiking sleeping bag is becoming easier as the technology for synthetic insulation is improving. While I still recommend responsibly sourced down if superior warmth and weight are your highest priority, many alternative options will suffice for most. 

Below are some points to consider if you’re looking to find the most sustainable option for your hiking sleeping bag. 

What Materials Are Being Used

While it’s not always easy to determine whether the materials used to make our beloved products are sustainable, there are a few words we can look out for. 

Obviously, anything that states it’s recycled is a big win, as is a product with a Bluesign Approved label. 

Is The Down Ethically Sourced?

When you’re shopping for a down-filled sleeping bag, the brands will state whether they source ethical down. Look out for the words Responsible Down Standard (RDS) and Traceable Down Standard (TDS).

These standards state that the sourced down has not come from ducks or geese that have been subjected to any unnecessary harm or distress. As in, no live-plucking or force-feeding. This down comes as a by-product of the meat industry.

Note: The hiking sleeping bags suggested in this post will only be from brands that have an RDS or TDS label.

Fair Trade 

Fairtrade refers to the promise that traders in developed countries are ensuring the producers in developing countries are being paid and treated fairly. This is an extremely difficult metric to figure out as in many cases, even the brands trying to do the right thing in supporting fair wages and conditions have no idea what the factories are actually doing. 

However, if a brand has the Fairtrade logo then this is a great start.

Durability and Longevity

Durability is another massively important factor in sustainability. Even if a sleeping bag is made with sustainable materials in an environmentally conscious way, if the quality of the sleeping bag is poor then this results in a short life span which adds to waste and overconsumption. 

Don’t forget the age-old saying – you get what you pay for!

Company Policies

Company policies, such as repairing faulty or damaged products, can make a huge impact on sustainability. Many of the companies at the forefront of sustainability will offer a lifetime repair warranty and when the sleeping bag becomes unrepairable, they will take it off you to recycle it and provide you with a discount for a new purchase.

4. Sea To Summit Spark III Sleeping Bag

Best Ultralight Hiking Sleeping Bag

The Sea To Summit Spark III sleeping bag excels in weight, being the lightest sleeping bag option on this list by a long shot. They succeed in the low weight by adding nothing that’s not strictly needed and using premium RDS approved 850+ loft.

However, you will sacrifice a few things with a weight that low and the most noticeable ones are the 10D nylon outer shell – you can literally see the feathers inside – and the 1/3 zipper that makes it quite annoying to get in and out of. 

The women’s equivalent to the Spark III is the Flame III

What it’s good for:

The Sea To Summit Spark and Flame III sleeping bags are great companions for ultralight hikers, however, you’ll want to ensure you don’t take it outside the tent with such a low denier count!

On top of a lower price tag, the Dragonfly 400 is sustainably constructed with a Pertex Quantum 100% recycled nylon outer that is made using their tough Y Fuse technology for increased durability.

6. Nemo Forte 20 Synthetic Sleeping Bag

Best Synthetic Sleeping Bag

The Nemo Forte 20 Synthetic sleeping bag is made from 80% post-consumer recycled (PCR) content and will keep you feeling snug as the temperature nears zero. You’ll find Nemo’s signature ‘Classic Spoon’ shape for the Forte, which allows more room around the elbows and knees for side sleepers. 

The only downside to the Forte 20 Synthetic sleeping bag is its bulky nature. Being such a warm sleeping bag with synthetic insulation, it doesn’t pack down nearly as small as a down sleeping bag of the same comfort rating. However, the price difference could be worth the extra bulk! 

What it’s good for:

The Nemo Forte 20 is an affordable synthetic option for cool nights in the mountains. The women’s will keep you warm well below zero while the men’s will reach 0 comfortably. It’s a great sleeping bag for sustainability and comfort, however, ultralight hikers may have an issue with its weight and compressed volume.

8. Mammut Perform Down Hiking Sleeping Bag

Mammut concentrates on luxury and comfort when producing their sleeping bags and leaves nothing out! You’ll find the Mammut Perform Down sleeping bag has all the bells and whistles while managing to stay lightweight. 

The sleeping bag hood is made with a comfortable and soft material that reduces noise, an easy-to-use magnetic clip attaches to the middle zipper to avoid cold drafts and the zipper location allows for ease of movement and temperature regulation. 

Not only that, but they also provide a gift package with the sleeping bag that includes earplugs and an eye mask. 

Note: The Mammut sleeping bag temperature rating is all over the place and varies from website to website. Even though the bags have ratings in their names,  I have found that all seem to use the limit rating, even the women’s bags. To really discover the comfort rating for these sleeping bags, you need to do a little digging. Below is the comfort rating for the Perform Down -7 sleeping bag and the Women’s Perform Down -10 sleeping bag.

What it’s good for:

The Mammut Perform Down sleeping bag is the ideal choice for summer and shoulder season adventures when the temperature might dip towards zero. This sleeping bag is a winner if comfort and luxury are of the highest importance to you, without having to lug around extra weight!

9. Nemo Kayu 15 Hiking Sleeping Bag

The Nemo Kayu 15 Sleeping Bag is another lightweight option with a few added features to increase versatility. The stand-out feature is the ‘Thermo Gills’ that are located on the front and can open to let heat out without letting a cold draft in. 

It is important to note that with the Nemo sleeping bags, the number in their name refers to the temperature rating in Fahrenheit. However, the women’s number is the comfort rating and the men’s is the limit rating. You’ll find a big difference in warmth between the men’s and women’s and we recommend going off the comfort rating for both rather than the limit rating for the men’s. 

What it’s good for:

The Nemo Kayu 15 is a slightly more affordable lightweight option for backpackers looking to save a little weight without sacrificing warmth or durability. 

Price: $520 $480 AUD
Temperature Rating: Women’s: Comfort -8℃ | Men’s: Comfort -3℃

10. Macpac Escapade 500 Hiking Sleeping Bag

The Macpac Escapade 500 is a budget-friendly option that will keep you warm in mild conditions. This 3-season hiking sleeping bag has a relaxed rectangular shape that is ideal for those that rather have a little extra room to move.

I currently own the Macpac Overland 400 (now discontinued) which has the same temperature rating as the Escapade 500. I now use it solely for summer adventures because I find it’s not warm enough if the temperature dips near 0. However, I can vouch for the durability of these sleeping bags as I have taken mine with me on a few sunrise summit missions and haven’t ripped it yet!

What it’s good for:

The Escapade 500 doesn’t stand out in any specific component, but with its minimalistic design and lower price tag, it’s the perfect entry-level sleeping bag for warmer climates

11. Sea To Summit Traverse III Sleeping Bag

The Sea To Summit Traverse III is a versatile and durable synthetic sleeping bag with multiple ventilation options for ease of temperature regulation. Due to its technical construction and synthetic insulation, it performs exceptionally in the wet. 

However, with a durable and water-resistant design comes a hefty weight. This is one of the heaviest bags on this list, but also one of the most affordable for its warmth rating

The women’s equivalent to the Traverse is the Venture, however, the Venture II is closer to the Traverse III when comparing warmth so those are the two listed here.

What it’s good for:

The Sea To Summit Traverse and Venture sleeping bags will benefit you if you’re often finding yourself hiking in wet and cold conditions, such as the Kosciuszko National Park. If weight isn’t an issue, this bag will keep you warm when the temperature dips and the moisture rises.

17. Patagonia Fitz Roy Sleeping Bag

As we’ve come to know and love, when you buy Patagonia you know it’s going to be as sustainable as possible and ethically made. That’s no different for the Fitz Roy sleeping bag which has 100% recycled fabrics as well as being Fair Trade certified sewn. 

The Fitz Roy sleeping bag is built without any unnecessary add-ons to save weight where it can and has done quite nicely. With an overall weight of 795g, it’s one of the lightest options on this list.  

The only downside we have noticed through our research is the lack of temperature ratings that we can compare to other bags. Through reviews, it seems that the rating must be the limit and therefore not ideal for temperatures near zero. This does make it quite an expensive summer option. 

What it’s good for:

The Patagonia Fitz Roy sleeping bag has a low weight that will be warmly welcomed on extended summer multi-day hikes. With a wider shape and a baffled design to keep the down evenly spaced, it’s a great option for those that don’t want to find cold spots but need a little extra room to move.

Final Thoughts On The Best Hiking Sleeping Bags

Well, congratulations if you made it this far and I hope this has cleared up any confusion you may have had regarding sleeping bags and their components. Luckily, choosing the right sleeping bag is easier than gear such as hiking boots and you shouldn’t need to engage in much (if any) trial and error. 

Remember to figure out the warmth you need before considering any other factors and as long as you choose one that has a warmer comfort rating than you ever plan to sleep in, you’ll be cosy! 

If you have a favourite sleeping bag that you believe should be on this list, we’d love to hear about it in the comments below! On the contrary, if you’ve got any feedback for a sleeping bag that is on this list, that information would be greatly appreciated as well.

Happy Camping!
