  • Shell: Synthetic
  • Water-Repellent Fill
  • Covered Zippers (to lock out cold air)
  • Compatible with other REI Sleeping Bags (zip them together for double the warmth!)


For its size and weight, the REI Joule is incredibly warm. It has several design features to keep you nice and toasty. It has a contoured hood, designed to fit snugly around your head and lock in warmth. The hood also includes a piece of fabric designed to cover some of your face (while allowing you to breathe, of course!). Plus, it is stuffed with super warm duck feathers, also known as duck down.

This bag is also water repellent and breathable, making it great for many different conditions.  And it’s even available in an only slightly heavier wide size, allowing you to opt for more wiggle room while keeping your pack weight down.

  • Generous Knee and Foot Room (for increased comfort and thermal efficiency)
  • Zipper Cover and Anti Snag Strip (for easy zipping)
  • Insulated Shoulder and Neck Yoke (which fits around your neck and shoulders to prevent heat loss)


This sleeping bag offers a bit more mobility for those who tend to toss and turn at night. It is spacious in the knee and foot area, meaning that you can switch positions more easily than with other, slimmer bags. Even with its wider design, this bag will still keep you toasty, even on chillier nights. 

Rated at 17 degrees F, the goose down filling will still keep you warm. Plus, its insulated yoke (the part of the bag that fits around your neck and shoulders) is designed specifically to prevent heat loss, keeping you comfortable and warm all through the night.

The North Face Inferno

This sleeping bag is the real deal! If you plan to camp in cold areas or more than just spring and summer, this might just be the pick for you. The North Face Inferno is one of the warmest sleeping bags on the market. It promises to keep you warm in negative temps and its specially treated down filling keeps you from getting wet and cold.

This sleeping bag has a higher price tag, but its thermal abilities are well worth it if you get cold easily or plan to do cold-weather camping. Plus, it is so good at keeping you warm that you won’t need to bring as many layers for sleeping. The Inferno is really all you need.

  • Water-Repellent Finish


With its high level of quality and moderate price tag, the Marmot Ouray is a great pick for the value-seeking backpacker. This super warm bag features a duck feather fill as well as full-length zipper covers and a shape designed to hug your body and lock in heat. Plus, it has a snag-free zipper and is water repellent. 

For a basic starter sleeping bag, this is a great buy. It offers all the basic features to keep you warm and comfortable in many different conditions while coming in at a reasonable price.

Those who purchase the Marmot Angel Fire bag will not be disappointed. It provides the perfect ratio of roominess versus warmth. Specifically designed to keep a woman’s body warm, it has extra fill in high heat-loss areas and a curvy shape to hug your body and trap heat.

As a bonus, you can zip this bag together with other Marmot bags for double the warmth! Plus, the neck and hood of this bag are filled with down and have an easy-to-access cinch cord to keep heat locked in.

  • Shell: Ripstop Nylon
  • Comes in Petite Size
  • Breathable Shell
  • Exterior Loops (for hanging and/or drying)


The Big Agnes Oliphant sleeping bag is The Adventure Junkies pick for versatility because it is one of the warmest on the market, but it is super breathable at the same time. This combination makes it ideal for a range of weather and backpacking conditions.

One of the features that takes this bag’s versatility beyond that of most all other sleeping bags is its internal liner loops, which allow you to attach an extra liner if you so desire. Attaching a liner will take this bag from warm to super warm, and the liner can be easily removed when you are backpacking in warmer weather. We also love this bag for those wet-weather days. If your Big Agnes Oliphant bag gets wet, it’s not a problem. The breathable fabric and hanging loops are designed for a quick and easy drying process.

Another great buy, the Outdoor Vitals Atlas Sleeping Bag comes in a variety of color options and temperature ratings to best suit your personality and adventure type! At only $100, this sleeping bag will keep both you and your wallet happy. 

It features heavy zippers to lock out cold and keep in warmth, as well as easy to maneuver ventilation flaps for those warmer nights. It is lightweight and comes with a free compression bag to save you room in the rest of your pack. This bag also comes with a lifetime warranty, so you really can’t go wrong with this buy.

Another Adventure Junkies pick from Big Agnes is the Sidney. Rated to keep you warm in temperatures as low as 25 degrees F, and featuring interior loops to allow for the optional addition of a thermal liner, this bag is sure to keep you toasty in lots of conditions.

The synthetic material used to line this bag is another feature that makes it a pick for our list because it is soft and comfortable and is guaranteed to help you get a dreamy night’s sleep! This bag also comes in a petite size, for our smaller outdoor adventurers.

  • Temperature Rating: 35 Degrees (F)

When it comes to price, the Winner Outfitter’s Mummy Sleeping Bag really cannot be beat. It’s lightweight enough for backpacking and will keep you warm in temperatures as low as 35 degrees F. It also compresses to less than 12 inches by 11 inches so you can easily fit it in your pack.

This product also comes with the Winners Outfitters guarantee: If you are unsatisfied with the product for any reason, they will take it back and issue a full refund, no questions asked.





Temperature rating is perhaps the most important thing to consider when purchasing a backpacking sleeping bag. It can get pretty cold at night in many popular backpacking destinations, and a cold night’s sleep makes for a bad night’s sleep, and a bad night’s sleep could in turn make for a bad next day!

Don’t mess around with the cold. Think about what kind of climates you will be backpacking in and make sure you choose a bag with a lower temperature rating than what you plan to be hiking in. For more on the meaning of sleeping bag temperature ratings, see REI’s super informative article, Understanding Sleeping Bag Temperature Ratings.



When it comes to quality sleeping bags, a higher price point is often an indicator of a warmer bag. However, that does not mean that you need to spend a fortune, especially if you don’t intend to camp in cold weather. For many adventurers, a cheaper bag with a higher temperature rating is sufficient. If you plan to camp in the fall, winter, or in Northern climates, though, you may want to invest in a more expensive bag that is sure to keep you warm.



As is true with any backpacking purchase you make, weight is an extremely important factor to consider when buying a sleeping bag for your next multi-day trip. You don’t want to be lugging something heavy around in your pack, especially because you’ll need a lot of other supplies, too. That being said, if you plan to take shorter backpacking trips, weight may not be as important to you. Sometimes lighter sleeping bags do not provide as much warmth as heavier ones. Check the technical specs for the bags you are considering and think about the length of treks you will be tackling when deciding how heavy or light of a bag you want to buy.



Fill is another great indicator of how warm a sleeping bag will be. Almost all of the sleeping bags on this list are filled with either goose or duck down. Both offer benefits, but they do have some key distinctions. For an in-depth look at the differences between the two, check out The Lowdown on Goose Down vs. Duck Down.

How well a sleeping bag locks in heat.
