How We Test & Methodology

We test camping sleeping bags along four different dimensions – warmth, comfort, packed size, and features – to assess and compare performance.

COMFORT

For sleeping bag comfort, we evaluate the bag’s shape and size, looking at how mummy, rectangular, and hybrid designs accommodate different sleeping styles and body types. We assess the softness of the interior fabric for its against-the-skin comfort. We also examine how roomy a sleeping bag is, particularly in the shoulders and through the foot box, to make sure there’s enough space to turn over. We test the effectiveness of the zipper system for ease of use and snag resistance, as a smooth-operating zipper enhances overall comfort.

WARMTH

For warmth, we test the sleeping bags in all sorts of conditions, from 0°F to upwards of 70°F to verify temperature ratings are accurate and a bag is reliable. Additionally, we assess the design features that help retain warmth while you sleep, like draft collars, hoods, zipper baffles, and baffle shape which are crucial in preventing heat loss. We also consider the shell material’s durability and water resistance, as these elements protect the insulation and maintain warmth in damp conditions. We also evaluate the fill loft and weight of each bag, (a higher loft and higher fill weight indicate better insulation and warmth).

PACKED SIZE

Packed size is less of a priority for camping than backpacking but size still matters for storage and transport. We look at the type of insulation and its loft, looking for high-loft down and advanced synthetic fills that compress well to save space in the trunk. Next, we measure the packed dimensions and weight and also consider if the sleeping bag uses compression sacks, straps, or a stuff sack that can dramatically reduce its volume without damaging the insulation.

FEATURES

When it comes to features on sleeping bags, we start by assessing internal and external pockets, evaluating their size, placement, and accessibility for storing small items like phones, chapstick, and headlamps. We look at the functionality of wrap-around zippers, ensuring they provide versatile ventilation options and easy entry and exit, and glow-in-the-dark zipper pulls earn extra points for visibility and ease of use in low-light conditions, adding convenience for nighttime adjustments. We also consider extra features like built-in pillow attachments, pad attachments, and torso or foot vents that contribute to the sleeping bag’s comfort and usability.

Analysis & Results

We outline the results of our testing process below and discuss top performers for warmth, comfort, packed size, and features.

VALUE

We look for sleeping bags that deliver top-tier performance to make sure you get the most out of your investment – regardless of the price tag. Although some sleeping bags are just downright less expensive with above-average performance, premium bags can often pay off in the long run with extended durability and higher quality. 

We’re huge fans of the REI Trailmade 20. This model offers an awesome value for only $100 – it’s comfy, warm, comes in a ton of inclusive sizes, and is lightweight enough for both car camping and short backpacking trips. We like the simple feature set, quiet material, and lightweight construction, making it a fantastic choice for campers who want flexibility on a budget.

Also consider the Teton Sports Celsius XXL 0°F. This is one of the warmest,  most spacious bags we’ve ever tested for such a competitive price. The extreme cold-weather capability and crazy durability of this one makes it an outstanding value for those needing a larger, ultra-warm bag. Rated for 0°F, its massive loft is built for the coldest temperatures and the fleece-lined interior rivals our favorite cold-weather sheets at home. Despite its large size, the Celsius XXL remains affordably priced for exceptional warmth.

Finally, The North Face One Bag offers unparalleled value with its innovative modular design. This is one of the most expensive bags on our list, but it’s essentially 3 bags in one thanks to a layering system built for a huge range of temperatures: 5°F, 20°F, and 40°F. Its combination of synthetic and down layers can be used together or separately in mild to sub-zero conditions. The versatility and performance it offers is a cost-effective investment for serious adventurers who camp year round.

COMFORT

When it comes to spaciousness and room to move, our top choices are the ALPS OutdoorZ Redwood -10, the Teton Sports Celsius Grand XXL 0F, and the REI Siesta Hooded 20. All of these bags are rectangular shaped – as opposed to more restrictive mummy bags – so they provide a ton of extra space to toss, turn, stretch out, and change positions while you sleep.

That said, the NEMO Jazz Double and the Kelty Tru.Comfort 20 are the most spacious sleeping bags on our list since they’re designed for two people – or one person and a dog – who want a comfortable shared sleeping experience.

We prioritize bags with soft interior linings to maximize comfort, which is also where the ALPS OutdoorZ Redwood -10 and the Teton Sports Celsius Grand XXL 0F stand out. They feature soft internal linings, whether synthetic material, flannel, or brushed flannel that offer a cozy, bed-like feel. The REI Siesta earns top marks for comfort too, thanks to a giant blanket-fold feature that zips down partially on both sides for a blanket-like feel that adds a bit of extra warmth and comfort for a snuggly night of sleep.

WARMTH

You won’t find a warmer bag than the ALPS OutdoorZ Redwood -10. This model easily withstands extreme cold temperatures down to -10°F thanks to a heavy-duty cotton canvas outer shell and brushed cotton flannel liner that provides exceptional warmth. The bag’s massive size and quilted construction trap heat effectively, while the draft tubes along the zippers and around the shoulders minimize heat loss. The combination of quality materials and stellar construction makes this bag our go-to for the absolute coldest conditions.

The North Face One Bag is another outstanding choice for warmth. The modular design allows three interchangeable layers, so it can adapt to various temperature ranges, making it suitable for sub-zero conditions when fully assembled. The synthetic and down layers provide excellent warmth and versatility and perfectly-placed draft collars and a cinchable hood enhance heat retention. Plus, the ability to configure the layers based on the weather offers a customizable warmth experience.

Another of our top choices, the Teton Sports Celsius Grand XXL 0F, is built for freezing temperatures rated down to 0°F. It features some of the loftiest synthetic insulation on the market, which offers good warmth even in damp conditions. The bag’s mummy shape, oversized hood, and full-length zipper draft tubes retain heat effectively. And, we love the brushed flannel lining to add a cozy feel with double-layer construction for consistent warmth all night.

We highly recommend the Mountain Hardwear Bishop Pass 15. This bag uses high-quality 650-fill-down insulation, which provides an excellent warmth-to-weight ratio. The bag’s mummy shape, contoured foot box, and insulated draft tube help maintain warmth, and the lightweight yet durable construction makes it ideal for sleeping in cold conditions where warmth and weight are priority.

PACKED SIZE

If you’re looking for a bag that packs small, insulation type and fill power matter for compression. That’s why both the Kelty Cosmic Down 20 and Mountain Hardwear Bishop Pass 15 are at the top of the list. They utilize down insulation, which is highly compressible and packs down to a smaller size compared to synthetic fills.

The fill power of their down – 600 fp for Kelty and 650 for Mountain Hardwear – contributes to their ability to shrink down. Lightweight materials in the shell and liner also play a crucial role in overall packed size, and these ones benefit from the use of lightweight nylon, which compresses better and occupies less space than other materials.

Two very close alternatives are the NEMO Disco Endless Promise 30 and the Therm-A-Rest Boost 650. They don’t quite achieve the same compact size, but it’s close, and we’re splitting hairs here. They also utilize lightweight materials and highly-packable designs perfect for backpacking or car camping.

FEATURES

The most feature-rich sleeping bags we tested are The Therm-A-Rest Boost 650, the North Face One Bag, the NEMO Jazz Double 30, and the REI Siesta Hooded 20. All four bags feature oversized hoods as well as large neck baffles and draft tubes that enhance warmth and comfort. They include internal pockets to stash small items like your phone or chapstick for fast access. The mummy-style hood of the Boost 650 and The North Face One Bag provides a snug fit, while the Jazz 30 Double has a hood big enough to hold two full-sized pillows.

The Boost 650 is full of lightweight zippers that offer unique and handy features. Unzip the center of the back to expand the width, transforming it from a mummy bag into a spacious car-camping bag. Unzip two zips on the side to vent heat or completely stick your arms out for unrivaled dexterity while staying warm inside the bag, and completely zip the bag down to the base of the footbox and use it as a quilt.

The North Face One Bag has a zipper that extends all the way around the perimeter to customize temperature regulation and breathability. We also appreciate the glow-in-the-dark zipper pulls that make it easy to adjust the bag when it’s dark.

The NEMO Jazz 30 Double is perfect for two campers with zippers that run down the side for separate in and out, as well as ventilation for each person. An included polyester sheet adds warmth and bed-like comfort. This one also has a mattress sleeve on the underside to prevent slipping and sliding at night.

How to Choose a Camping Sleeping Bag

CHOOSING A TEMPERATURE RATING

How do you choose the “right” temperature rating? Many things contribute to how hot or cold you might feel, like packing the right clothing, staying hydrated before bed, eating plenty of calories at dinner, altitude of your campsite, and especially the insulation of your sleeping pad / mattress. 

We’re confident all of the bags on this list will keep the average camper comfortable in typical temperate summer conditions, with overnight temps mostly in the 40s and 50s, with some bags rated for much lower or a little higher. However, if you already know you’re a hot or cold sleeper, take that into account when weighing your options.

• Temperature Rating: Most sleeping bags have a number listed after their name: for example, the NEMO Jazz 30. As mentioned above, this number represents the lower limit of the bag, which is around 10-15°F less than what is comfortable. Look for bags with a standardized EN Comfort Rating. The EN rating gives a more practical, real-world idea of how the bag will feel to the average sleeper. That said, it’s rare to see EN Comfort Ratings on frontcountry camping bags. If you don’t see a comfort rating, just add 10-15° to the temperature rating listed by the manufacturer.
• Increase your Temperature Rating – Remember, you can always add layers to increase the warmth of your bag. If you sleep cold or know there will be a major drop in temperature, simply throw a camp blanket over the top, use a silk bag liner on the inside, or simply wear additional layers to add warmth. We recommend sleeping in base layers and a warm hat on really chilly nights. Also consider eating food right before bed so your body has calories to burn, drinking plenty of water to keep hydrated, or even sliding a hot water bottle inside your sleeping bag a few minutes before you hop in.

WHERE DOES THE DOWN COME FROM?

Down is the soft, fine layer of feathers beneath the outermost plumage on ducks and geese. These tiny feathers help keep the birds warm, especially in very cold weather. Most down comes from birds used for meat, and a large portion of the world’s down – around 70% – is supplied by China.

DOWN FILL POWER VS. SYNTHETIC

Fill power (fp) specifically refers to the quality of down insulation in down sleeping bags – note that this rating doesn’t apply to synthetic bags. Higher numbers mean the down is lightweight, compresses better, and usually costs more. Ratings above 800-fill-power are top-notch. If the number is lower, it’ll likely cost less, but won’t be as warm for the weight.

When it comes to synthetic insulation, quality is measured by the type of material used and the steps taken in its construction. Synthetic bags may use terms like “weight” or “thickness” to describe their insulation quality. As a result, measurements are harder to compare and gauge for synthetic sleeping bags.

BAG LENGTH & WIDTH

Sleeping bags generally aim to eliminate areas of dead heat – pockets of interior volume that your body has to expend energy to keep warm. Mummy bags, because of their tapered bottoms and more snug fit, tend to feel the warmest, although they can be narrow and restrictive for sleepers who like to spread out. Unfortunately, mummies rarely come with wide options, so you’ll want to look elsewhere if the bag is too slim.

Rectangular and wider bags may feel a bit colder in chilly temperatures due to cold spots in the corners or at the edges. However, if you’re a belly or side sleeper, or tend to move a lot at night, a wider orientation will feel more natural and comfortable. Plus, many rectangular bags have zippers that extend the entire length of one side for venting. Many have zippers that wrap around to the opposite corner so they can open up into a blanket or quilt, offering maximum versatility for ventilation and comfort.

In general, we recommend choosing the wider version of most sleeping bags, regardless of your sleeping position. In our experience, the more room you have to roll over and adjust, the more comfortable you’ll be.

DWR

DWR, or Durable Water Repellent, is a treatment for the outside fabric of your sleeping bag – down and synthetic – that adds a layer of water resistance. When this treatment is done regularly, instead of soaking into the fabric, water will bead up and stay on the outer shell. By no means does this make your bag fully waterproof, but it adds an important bit of extra protection. Many sleeping bags already come with a DWR coating, but just like rain jackets and rain pants, it eventually wears off and you’ll need to reapply it. To learn how, check out our guide How To Clean & Wash Your Sleeping Bag, including steps on reapplying DWR.

WASHING & STORAGE

When it comes to durability, down is excellent, but it loses efficiency over time as it gets oily, dirty, and compressed. Synthetic materials may last a bit longer, but it’s lifespan also depends on proper storage and maintenance so it can last year after year of regular use.
