Recent Warm Weather Synthetic Sleeping Bag Reviews

Marmot Trails

rated 5 of 5 stars My Marmot Trails sleeping bag is a favorite for warm nights. I've used the Marmot Trails sleeping bag on many occasions over the past decade. It's been perfect for warm summer nights as well as those times on someone's couch. It is easy to launder — regular washer/dryer. When traveling by car and luggage space allows, I take it on trips in addition to a cold weather bag. Generally, if a cold night occurs, I'd rather add more warm layers of clothing than be stuck with an overly insulated cold weather… Full review

The North Face Allegheny

rated 4 of 5 stars So nice and lightweight and not bulky at all. Nice and lightweight and rolls up in seconds. Full review

Ferrino H.L. Micro

rated 5 of 5 stars Ferrino has always had amazing products. Ferrino is my favourite brand for anything outdoor. Also Ferrinos products never break, they are very reliable! Ferrino is an amazing brand that I can always trust when purchasing. Even if anything breaks they customer service is outstanding! Full review

The North Face Dolomite 2S 40F

rated 3.5 of 5 stars Lightweight sleeping bag. For those who can't tolerate a mummy bags claustrophobic feel, this rectangular bag is very comfortable . I am 220 lbs and 5-11 and had plenty of room. The temp. rating is right on the money at 40 degrees. Stores a little on the big side. Temp rating is right on. First night used a silk liner and got too warm, next night was colder, and I had already given up my liner to my son. It got a little cold and I need to get another layer on. There is plenty of space, since it… Full review

Mountain Hardwear Women's Lamina 35°

rated 5 of 5 stars I've taken this sleeping bag on several trips with me and have been pleasantly surprised by how warm it is for a 35 degree bag (although there have been times when I wished it were warmer) and how well it packs down. I've used this sleeping bag for a 10-day trip to the Boundary Waters in early May when there was still some snow on the ground, and while I could have used a liner, I slept pretty well in this bag (minus the wetness from the constant rains we got too). In my experience it didn't dry… Full review

REI Travel Sack +55

rated 3 of 5 stars A lightweight, relatively inexpensive "55°F" sleeping bag/liner that provides me with a number of options in summer and winter conditions. Summary I have owned and used this sleeping bag for several years for summer camping. I have frozen my butt off in it with a night time low of 60°F, making me question its "55-degree" rating. However, I have discovered several unconventional uses for this bag that made it worth the investment. I've never regretted owning this piece of gear. Specs The bag is… Full review

Mountain Hardwear X-Country 40

rated 5 of 5 stars Lightest, smallest-packing, synthetic bag I've seen. This a great synthetic bag. It's super small and light (1 lb., 14 oz.) and packs down to almost the size of a football.  The only drawback is it's not for the cold winter months since it only goes down to about 35-40 degrees. No drafts, as roomy as an average bag (not as light as a Big Agnes, but good size), easy in and out. No complaints in 3-season use. Full review

The Backside Backsider X-Fibre 35

rated 4.5 of 5 stars Packs small and light and keeps you warm. I have used mine down to 20 degrees with a liner. I have used my Backside on canoe trips in the Boundry Waters, Minn., and down the Eleven Point River in Missouri. I cannot pack as much as I used to so I appreciate the lower weight and the ability to compression bag it down to a small size. Never had an issue with being warm and I have used it with temperatures in the 20's. Full review

Outbound Bike & Hike +44°

rated 4 of 5 stars This bag rolls down to almost nothing and it comes with a compression sack to get it even smaller. Weighing in under 2lbs it's great for a pack, and its price being almost too good to pass up. Although it's rated at 44°F I wouldn't trust it much past mid 50s. That being said, I would still recommend this bag for late spring through early fall to keep you sleeping sound. This bag rolls down to almost nothing and it comes with a compression sack to get it even smaller. Weighing in under 2lbs it's… Full review
