Recent Warm Weather (above 35°F) Sleeping Bag Reviews

Western Mountaineering EverLite
Excellent choice for overnight bivy summer summits, bikepacking etc. Best weight-to-warmth ratio. Have 6.6ft version.Used on Mt Moran in summer, multi-day trip to Big Horns in summer, sleeping in the car in the fall while driving cross country. On all occasions, I slept in dedicated long underwear, long-sleeve top, and wool socks. Haven't had any condensation issues. Haven't had the need to wash (sleeping in dedicated long underwear, top, and socks prevented stinking up the bag). I am 5 ft 9 in… Full review

Sea to Summit Traveller TrI 50°F
A versatile and quality piece of sleeping gear that can be used in many different ways and provide warmth even in slightly-bellow-rated temperatures. Good option for lightweight backpackers campers and travelers who sleep in various conditions and settings (hammock, tent, hostels, etc.). Context I live in a tropical country and temperatures here hardly ever go below 30°F, even at the height of the winter and in the wilderness and rural areas where it’s always colder. Therefore, I can do fine… Full review

Western Mountaineering EverLite
The Western Mountaineering EverLite is a lightweight warm-weather down sleeping bag. A versatile piece of gear, it can also be used as an inner bag or an overquilt. I bought my Western Mountaineering EverLite sleeping bag about 3 years ago as part of my 4lb summer bag/pad/tent setup, and I’m thoroughly impressed with it. It keeps me warm below the 45°F rated temp, packs down way smaller than I’ve needed, and the tapered design makes it very versatile—it can be used as a sleeping bag, blanket,… Full review

Wenzel Monterey 30°-40° Hooded Sleeping Bag
A good value sleeping bag that stays warm. Good for 2-3 seasons. For the price, this is a good bag. Well crafted, and very warm. The fleece inside is a nice touch making you feel instantly warm when you get inside. At 6 pounds this isn't going to be someone's backpacking bag, so Wenzel wisely went the other way adding features like a leverage loop on the stuff sack to help get the sleeping bag in and out, a big hood (great if you're a little claustrophobic in a smaller bag), elastic bands to keep… Full review

Wenzel Lodgepole 40° - 50° Sleeping Bag
High quality sleeping bag. The sleeping bag is comfortable, lightweight, and kept me warm. Full review

Wenzel Lodgepole 40° - 50° Sleeping Bag
I cannot tell you how happy I am to have this new sleeping bag! I’m now sleeping so much better while camping. I love having the extra room!! After sleeping in a mummy bag for a few years, I am So Excited to be back in comfort. I also love how soft the material is too. Full review

Wenzel Lodgepole 40° - 50° Sleeping Bag
The Lodgepole's roomy, oversized fit will allow you to sprawl out while keeping you toasty between 40-50 degrees with its quick-warming brushed liner, cozy fleece collar, and fleece-lined footbox. I'm 5'3" and I am a stomach sleeper. I like to have a knee up and in this bag, I can actually put my knee up. This is the biggest plus about this sleeping bag. The fleece collar is great too. I used this in my camper with the ac on 66° so I was able to use it and not sweat to death. The zipper worked… Full review

Sea to Summit Traveller TrI 50°F
Enables me to go with a 40-liter pack for four days and three nights in summer. With this bag, I can get my summer sleep/shelter system down to around 4 1/2 pounds. The bag compressed (15 oz) in its Ultra sil compression sack (blue) on left with a Sea to Summit Ultralight Pillow (2 oz) in the sack also. Next to it is the Marmot Tungsten UL 1 (pole bag, tent body, fly in an ultra sil (yellow) and stake bag (2 lbs 9 oz), and the Nemo Tensor mummy sleeping pad in it's stuff sack (15 oz) on the far… Full review

Alpine Design 45-degree Micro Lite Mesa Rec Bag
Great addition to one's warm weather gear kit. $4 at Amvets seconds store. Tried to find Alpine Design on net, nothing! Used with no clothing to 45° F.; works well. With base layer, would go much lower. Wondering what the fabric and materials used are? The insulation factor is pretty good, must be some kind of fabric magic at work. Wonder what Alpine Design has to say about that? Anyone know how to locate that company? Full review
