Your sleeping bag is one of the most important pieces of gear that you will carry with you into the great outdoors. A cumbersome bag that’s bulky, inefficient, or excessively heavy will not only deplete your precious energy stores over the course of the day but may also impact your stamina, becoming a legitimate hassle as you trek up the trails. Whether you’re hiking, backpacking, or camping, a lightweight, high-quality sleeping bag, is an absolute must.
What exactly should you be looking for in an ultralight sleeping bag? The goal with a bag of this kind is to stay as warm and as comfortable as possible without substantially weighing down your pack. Ultralight sleeping bags will usually be 3lbs or less when compressed. They should easily fit in your pack and will unroll to provide you with a warm and viable sleeping solution under any number of circumstances.
Below, we will look at ten of the best ultralight sleeping bag options currently available. We have searched through hundreds of products to find sleeping bags that are warm, comfortable, extremely light, designed to be utility-friendly, and that also offer overall good value.
Outdoor Vitals is a newly emerging company with unique foundations that prioritize quality, sensibility, and utility. They state that their goal is to provide affordable outdoor gear solutions for adventurers who desire quality material composition and construction at reasonable prices. The Outdoor Vitals Summit 0°F Premium Down Sleeping Bag features thick insulation that’s moisture resistant, comfortable, and lightweight. It also sports a grid baffle design that locks the 800+ DWR coated down fill into place for better distribution of warmth. It rolls up to fit easily in your pack and comes with a limited lifetime warranty. Available in four neutral colors, this sleeping bag also includes a compression sack for quick and easy storage. It’s light, durable, warm, and easy to carry. Its quality design, premium material construction, and lightweight easy feel make the Outdoor Vitals Summit an impressive value product. On the downside, if you anticipate encountering freezing temperatures and want to have an additional liner for extra warmth, you’ll have to purchase it separately. The extra warm liner is not included with this bag. Other than that, this is a fantastic option that’s well worth the consideration of any hiker who prioritizes value and quality.
One of the most difficult obstacles to face when sleeping in the wilderness is the cruel and cutting wind. Nothing is worse than frigid gusts or icy breezes that can cut through your tent and infiltrate your sleeping bag, keeping you wide awake with your teeth chattering all night long. The Wenzel Windy Pass tackles the wind with an ergonomic design and draft shape that wraps you in toasty warmth throughout the night. It’s a snug mummy style bag that zips down the side so you can keep your back to the wind when entering and exiting. With a 0º rating, it can stand up to very cold temperatures with ease. Extra thick fill and an offset quilt pattern aid in capturing your body heat and holding it around you as you sleep. It’s an oversized bag as well, so even though it’s snug, you’ll find you have plenty of room to roll over. The polyester outer shell helps to keep you dry while the 3-inch shoulder collar keeps the cold out. It’s also an extremely inexpensive option. Still, this sleeping bag has some disadvantages. For starters, it’s not as durable as many of its more expensive competitors. Additionally, it’s not as easy to store as the Outdoor Vitals Summit 0°F Premium Down Sleeping Bag. However, if you want something that’s cost effective and will get the job done in a pinch, this is a great option.
Comfort and quality are not worth sacrificing when you’re exhausted and desperately in need of a good night’s rest. The Sea Summit Traveler TR1 keeps this in mind with its slightly tapered rectangular shape and 750+ loft down fill. It opens like a blanket, so you can use it in moments of leisure relaxation or at night. When you close it up, it keeps you extremely comfortable and dry with ease. The YKK zipper is awesome for both left and right-handed people. The collar helps to keep out wind and cold while the multiple drawcords allow you to pull it tighter in the places you need to. It’s also extremely easy to store and carry. It’s like a sleeping bag and down comforter, all rolled into one. Lastly, it’s designed from the best materials available. It’s a durable, versatile, comfortable, and utility-friendly sleep and leisure solution for outdoor adventurers of all kinds. On the other hand, this bag could be a bit warmer. It has a disappointing 50° F EN rating. The fill and design give you more comfort than warmth. It would be best for warm weather trips in the late spring, summer, and early fall.
Teton knows that it is hard to decide between thick loft and lightweight utility. They’ve designed the Trailhead to balance these principles masterfully, you don’t have to pick one or the other. The bag has a hooded mummy design that keeps you from losing warmth through your head as you rest. It also has a zippered draft tube shape and vaulted foot box that help to keep you warm and comfortable on the ground. The lightweight design and compact shape make it ideal for backpacking through rough terrain because you don’t have to worry about it catching or snagging as you navigate under trees or around brush. It’s also packed with an innovative microfiber to offer more loft, less weight, and lots of heat. The durable stuff sack included with this bag means no more wasted time rolling and folding. It’s safe to say that you don’t have to give up comfort in exchange for utility with the Trailhead. It even comes at a competitive price, making it a pretty good value. The only downside is its size. This is not an ideal option for users who are over 6ft.
This is a bag for serious adventurers. One look at the Western Mountaineering UltraLite tells you it’s for hardcore backpackers and hikers. A premium sleeping bag that has been designed to last a lifetime, this sleeping bag doesn’t mess around when it comes to protecting you in the wilderness. Interlocking draft tubes and a full down collar allow this bag to wrap snugly around you to seal in heat and keep you fast asleep. It’s also extremely breathable and water resistant. Its shell protects you and the interior down insulation from water and condensation. This is an absolute must if you’ll be encountering damp conditions of any kind. The spacing of the continuous baffles work to encircle the entire sleeping bag from one end of the zipper to the other. It has 16oz of 850 down fill for toasty warmth and an impressively comfortable 5+ inches of loft. All around, this is a fantastic option for the serious outdoorsman. On the downside, a bag like this comes at a price. Expect to pay a bit more for the quality design, and large size offered by this bag.
A lightweight and comfortable three-season option, this is the kind of sleeping bag that makes you sleepy just looking at it. It comes at a mid-range price and is constructed of warm and comfortable high-quality materials such as 20D non-rip fabric. It has 15 fluffy down quilt sections. The large oversized baffles provide lots of loft so you hardly feel the ground. It’s also light, so you won’t have to compromise when it comes to weight. If you find yourself a bit too toasty, just open it up and use it as a quilt for relaxation on the ground or in a hammock. It also comes with a limited lifetime manufacturer warranty. Another nice feature is the travel design. You don’t need a stuff sack or compression bag as it has sleeping pad straps that double as a cinching device. As far as drawbacks go, this bag is prone to snagging and isn’t as small when compressed as some of the other bags on our list. If you want super compact storage, you may want to go with something like the Western Mountaineering UltraLite. Still, this is a comfortable and multi-functional mid-tier sleeping bag that could potentially serve you for years.
With a shell of 10D UL Nylon treated with DWR, this bag is one of the driest and most durable options available. The liner is made of similar materials that give you a soft-to-the-touch feel and high-density weave quality. The 850+ loft dry down is a blend of 90/10 European goose down. This sleeping bag is of premium quality and unparalleled material construction. Sew-through transverse baffle construction means that it’s not prone to heat loss in any way. It also folds up small enough to be held in the palm of your hand. You may not even know that you’re carrying it. Sea Summit hasn’t let us down in any way with the Spark SP. It also comes in a few specifications, so you don’t necessarily have to pay out the nose for comfort and quality. If you choose the shorter version of this sleeping bag, you can literally save hundreds. On the other hand, if you’re tall, the short size may not cut it. You’ll have to opt for the more expensive, longer bag. However, even the larger and more expensive version is less expensive than the Western Mountaineering UltraLite, so if you’re looking to save on a premium piece of gear, this may be a good option.
The Hyke & Byke company does a great job of balancing utility, style, and value. This sleeping bag is filled with goose down and has been masterfully constructed to keep you warm without being too heavy. It is also soft and breathable. which makes this one of the most comfortable bags in its class. Additionally, this bag is great for saving on space and compresses nicely, which is surprising considering that goose down tends to be a heavier fill material. We like the way that the Hyke & Byke has managed to overcome the weight/comfort issue with this sleeping bag. You can also choose from four fun color patterns that really stand out; no matter which vibrant color combination you wind up picking, you’ll find yourself wrapped in whimsical and cheery comfort. On the downside, the smell of this bag is a bit much at first. Something about the DWR treated goose down gives it an industrial chemical aroma that takes a few days to disappear. If you buy this bag, we recommend letting it air out for a day or two before using it on the trail. However, once the smell dissipates, it’s a great lightweight sleeping bag that comes at a competitive price.
Another great Western Mountaineering product, this UltraLight sleeping bag boasts quality, comfort, warmth, and utility. Just like the other Western Mountaineering on this list, this bag has interlocking draft tubes for warmth distribution that will truly be appreciated on cold nights. Additionally, this sleeping bag features a full down collar, so you can wrap up and snuggle in for a full night of comfortable rest. It’s filled with around 16oz of 850 fill that’s not only lightweight but very easy to compress. You’ll have no issue at all packing up and getting ready to go. This is a high-quality sleeping bag for wilderness exploration, trekking, camping, hiking, backpacking, and more. The only disadvantage of this sleeping bag is the price tag. Still, for the quality and comfort, you can’t really beat it. It ultimately depends on the price you’re willing to put on a quality bag that offers a good night of sleep out on the trail. Another bonus: This is the smaller version of the bag, so you do save a bit o the price. If you are under 5ft 6in, you’ll save quite a bit. It’s ideal for women.
We know good value when we see it. That’s why the Ledge Sports has been featured on our list. After all, it isn’t often that you’ll find a 0°F sleeping bag of this quality at a price that’s so affordable. It’s a long, spacious, warm, and light sleeping bag. It has a great collar, so you can keep the cold out and cover your chin easily all night. Another thing we like about this bag is all its little extras. Sometimes, it’s the features that you don’t notice that matter the most. For instance, this bag has pockets, a contoured hood, and barrel locks that are so efficient, you may not even realize how much you use them. It’s the kind of sleeping bag that experienced outdoor types come to appreciate. It also compresses and stores easily for a more efficient packing experience. On the downside, this bag could stand to be a bit lighter. We recommend using it with a lightweight sleeping pad to save space and weight. Still, for the price, you’d be hard pressed to beat it.
