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

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

Big Agnes Horse Thief SL 35°

Love this thing. I've had this for several years with use along the lakeshore of Pictured Rocks and temps in high 30's. I wish they still made this bag so I could buy it for my kids now that they are backpacking also. To answer a couple of questions that may resolve issues posted up years earlier than this one: The pillow sack goes inside with you, not hanging off the edge. I believe some of the cold feeling people may be getting is from not using an insulated air mattress; I made that mistake also… Full review
