Crafted with durability in mind, the LEEF Ultralight Mummy Sleeping Bag is made from high-quality materials that can withstand the rigors of outdoor use. The zippers are sturdy and snag-free, ensuring easy access and exit from the bag. When it comes to packed size, the Brazos landed close to the middle out of all of the bags we tested.
There’s no fumbling in the night for the zipper pull, and you don’t have to worry about snags or heat loss (if the bag lacks a good draft tube). But in the end, we don’t see the zipper-less coleman canopy concept completely taking over the market. Put simply, the in-and-out convenience and ability to use the bag as a blanket with a full-zip sleeping bag is the better answer for most campers.
Liners typically cost between $30 and $60, and a couple of our favorite options are Sea to Summit’s Thermolite Reactor for mummy bags and their Silk-Cotton Blend Liner for rectangular models. To be clear, liners are totally optional and not everyone needs one, but they do offer added warmth and comfort and help keep your bag in good shape. For campers looking for a sleeping bag that can pull double duty on the occasional backpacking trip, we like Nemo’s Disco. With a 14-degree temperature rating, sub-3-pound weight, and decently packable build (it even includes a compression stuff sack), the Disco is fully serviceable for short forays into the backcountry.
And keep in mind the temperature rating is closer to a survivability rating rather than being comfortable and warm. Other factors to consider are your age—people typically don’t sleep as warm the older they get—and whether you are a cold or warm sleeper. Most campers stick to the warmer months for their outdoor adventuring, and as a result, most of the sleeping bags on this list are rated in the degree range.
With a rating of 9.5, this pad is suitable for all four seasons and provides excellent warmth and insulation, even in cold weather conditions. With its excellent combination of warmth, portability, and durability, the TETON Sports LEEF Ultralight Mummy Sleeping Bag is a reliable companion for your outdoor adventures. Whether you’re backpacking through the wilderness or camping under the stars, this sleeping bag will provide you with a comfortable and restful night’s sleep. Kelty’s popular Cosmic Down 20 has been a mainstay in their lineup for years and remains a popular choice among campers and backpackers alike. For starters, you get a respectable weight of 2 pounds 10 ounces, which is the lightest three-season option on our list (Kelty’s own Galactic 30 below weighs around the same but is far less versatile).
These sleeping bags also come with a convenient interior tuck pocket that lets you securely store small essentials, so you don’t have to sleep with them in your pockets. Browse through a wide collection of sleeping bags and find the perfect pick. As we touched on above, temperature ratings tend to be fairly generous and often require adding a sizable buffer to ensure you’ll stay warm throughout the night. For those who run cold or simply want to bring their bag into lower temperatures, adding a sleeping bag liner can help keep you cozy without breaking the bank. Liners are made of soft materials like fleece, wool, polyester, or silk and typically add around 5 to 15 degrees to the warmth rating of your bag. They also serve as a barrier between you and your bag’s interior, which can help boost lifespan (you can wash the liner after use rather than getting your bag dirty).
The TETON Sports LEEF Ultralight Mummy Sleeping Bag is a high-quality and versatile sleeping bag, perfect for backpacking, hiking, and camping adventures. Designed with ultralight materials, this mummy-style sleeping bag provides exceptional warmth and comfort without adding extra weight to your pack. In this metric, we also noted each bag’s packed weight and then scored each on how easily it rolled up and fit into its storage bag.
Additionally, integrated blankets, interior pockets for stowing small items like a headlamp, and draft tubes at the collar for trapping warmth are becoming more common. The Coleman Big Game is also durable thanks to its fiberlock construction that reduces cold spots and stops insulation from shifting. This sleeping bag is highly portable due to its easy-to-roll and pack design. If you don’t want a designed to heat up and/or store heat at night, the Coleman Sun Ridge comes highly recommended. When not using the Big Bay sleeping bag, store it in a large, breathable bag.
Keeping it compressed in the stuff sack for long periods can reduce the loft of synthetic insulation and cause the bag to develop cold spots. Coleman doesn’t provide the bag’s weight, but I weighed it in its compression sack at 4.2 pounds using my kitchen scale. Even though that’s only an extra few ounces, when you’re hiking over challenging terrain, you start feeling that added weight very quickly. If you want to use the Big Bay to test out backpacking on a one- or two-night trip, it’s manageable. The Big Bay is also available in a Big and Tall Contour version for $130, which is a few inches taller and broader in the shoulders, hips and feet, so it’s not quite a mummy bag and not quite a rectangle. I didn’t test the big and tall version, but the hood design, insulation, draft tube, neck collar and zipper are all the same.
