Cons: expensive investment, might be too large for smaller bodies
Western Mountaineering has long been the leader for cold weather sleeping bags and the Kodiak MF 0F Down Sleeping Bag takes the cake for its warmth, comfort, and size. What makes this bag stand out is the extra wiggle room, especially in the shoulders, which gives you plenty of room to move around if you’re a side or stomach sleeper. The extra room also gives you space to stuff your clothes and electronics inside your bag to stay toasty for the morning. What makes this bag even comfier is the full 7 inches of loft – this will make even the coldest of temperatures seem toasty!
For temperatures down to 0 degrees, you can’t find a sleeping bag better than this one. It may be at the top of your price bracket at around $730, understandably. But, with proper care, this sleeping bag should last you a very, very long time.

For less than $210, the Kelty Cosmic 20 Sleeping Bag has won many awards for being an all-around good-quality sleeping bag. Made with hydrophobic down, it’s lightweight but it will not perform as well in wet weather. Available in 0° and 20°, it’s one of the best sleeping bags for backpacking in its price range and a great option for new backpackers looking to get into the sport. It’s also available in a men’s version.
How to Choose a Backpacking Sleeping Bag
Picking out a new backpacking sleeping bag for any outdoor adventure can be super overwhelming. There are so many choices and so many features to consider, not to mention the price tag. So, we’ve put together this simple guide on how to choose a backpacking sleeping bag for your next great adventure. Hopefully, this makes your gear buying process easier.
Sleeping Bag Temperature Rating
The sleeping bag temperature rating is the first place to start when picking out a new backpacking sleeping bag. Think about when and where you plan to use it the most.
Sleeping bags can be broken down into three simple categories: summer, 3-season, and winter based on the temperature ratings shown in the table below.
Most people will be happy with a 3-season bag, which will keep you comfortable most of the year. Remember you can always zip down the bag for a summer camping trip or add a sleeping bag liner to your bag for an occasional winter camping trip. Most 3-season backpacking bags will list a European Norm (EN) testing rating with two temperature ratings known as the “comfort rating” and the “lower-limit rating”. EU ratings are standardized rating systems that keep temperature ratings consistent across brands.
Comfort rating is the lowest temperature at which the bag will keep the average woman or “cold sleeper” comfortable. Lower-limit rating is the lowest temperature at which the bag will keep a man or “warm sleeper” comfortable. (EN ratings are based on a sleeper wearing one long underwear layer and a hat, and sleeping on a single one-inch thick insulating pad.)
The number listed with most sleeping bags (example: Nemo Disco 30) is the EN Lower Limit which is usually 10-15 degrees lower than the EN Comfort Rating. So, for most people, the Nemo Disco 30 would be comfortable in 40F sleeping temperatures.
Sleeping Bag Shape
While the sleeping bag shape might not seem important, it is for two big reasons:
First, sleeping bags keep you warm by trapping air and holding it in a layer next to your body. Your body heats up this layer of trapped air to keep you warm. The less air space there is in the bag, the faster you warm up and stay warm! Picking a bag based on your body size and shape is important for efficiency and warmth. Roomier sleeping bags will often be heavier as well.
We recommend selecting a semi-rectangular bag or mummy bag which is versatile and can work for backpacking as well as car camping. Semi-rectangular bags are good for backpackers with larger frames or those who don’t like the constrictive feeling of a mummy bag.
To Quilt or Not to Quilt?
Some lightweight backpackers won’t even entertain the idea of a sleeping bag, and instead, opt for a camping quilt. Quilts are a lightweight backcountry option generally designed to be paired with a sleeping pad. It’s basically a blanket with a foot box that will keep you warm without any unnecessary insulation or weight. Quilts offer a better warmth-to-weight ratio since they cut out material that’s normally compressed under your body in a traditional mummy bag.
However, quilts are more drafty than mummy bags, so in cold or windy conditions we’d opt for a mummy bag. Be sure to check out Enlightened Equipment if you’re interested in going ultralight with a sleeping quilt.
Synthetic vs. Down Sleeping Bag Insulation
Since switching to a plant-based diet and eliminating all animal products from my diet, I’ve also questioned whether or not to switch out my outdoor gear made from animals – one of the biggest culprits being down (feathers). I have outlined the key differences and pros/cons below, but you can deep dive into the ethics of buying/using down in this blog post to help you understand the ethics and sustainability behind down feathers.
Synthetic Backpacking Sleeping Bags
Synthetic sleeping bags are usually insulated with polyester. Synthetic bags are quick-drying and still hold up to their insulation power even when damp or wet. Often, they are cheaper than down, and they’re non-allergenic. One of the downsides of synthetic bags is that they don’t compress as small as down sleeping bags, and they tend to be heavier than down (but that’s not always the case as technology improves). Also, polyester is usually derived from petroleum, although recycled polyester is now being made from plastic bottles and other recycled plastics for more sustainable options.
Synthetic sleeping bags are a good option for those that live a vegan lifestyle because natural down is produced from geese or ducks.
Down Backpacking Sleeping Bags
The biggest advantage of down over synthetic sleeping bags is that down bags tend to be lighter and compress smaller when packed away – key characteristics when you’re looking for the best backpacking sleeping bag. Generally down is more expensive than synthetic, and some people say it’s more durable, so it’s a long-lasting investment. The primary downside to down is that it loses its insulation power when it gets wet. So, it’s most suited for cool, dry conditions. However, many down sleeping bags are now coated with a water-repellent finish that will keep you warm and dry in damp conditions. Otherwise, down sleeping bags are a lightweight, warm, and packable choice for backpacking.
Most of the notable outdoor gear companies have instituted the Responsible Down Standard (RDS), or Global Traceable Down Standard (TDS). These standards ensure that the down and feathers used in these products came from animals that were treated well, and were not force-fed or live-plucked. All of the down sleeping bags listed here are certified to the RDS or TDS.
Other Important Backpacking Sleeping Bag Features
Sleeping Bag Hood
Having a hood on your sleeping bag can make or break your sleeping comfort. It can mean the difference between being freezing at night or toasty warm. Because the rest of your body is encapsulated in your mummy bag, your body’s heat would escape through the head without a hood. And, that defeats the purpose of the sleeping bag. So, opt for a bag with a hood if you want to be warm and comfortable. Most mummy bags and semi-rectangular bags come with a hood anyway. Quilts typically don’t have a hood, but many companies sell hoods as an add-on purchase. If you plan to backpack in warm environments always, it’s not as crucial. But, it’s better to be safe than sorry.
Some bags come with pockets that you can stuff with clothes to create a pillow. Others come with stash pockets to keep your glasses, a watch, headlamp, or cell phone nearby. Some bags also come with a pocket or sleeve designed to fit a sleeping pad so you don’t roll off in the middle of the night. The extra fabric might add to the total weight of the bag, but it’s a matter of personal preference and needs.
