Recent Warm Weather Synthetic Sleeping Bag Reviews

Deuter DreamLite 500

rated 5 of 5 stars Sweet, durable, comfortable, holds up to its ratings very well. If you don't have one, prioritize getting your Dreamlite. I truly love mine. For the guy with the cord issue, I thought the exact thing. Even considered sliding barrel lock up to perfecto tying a knot and cutting the extra off. But on one trip someone took my backpack. Luckily all my gear and sacks were in the tent with me. Man, figuring out how to lug my gear back out the trail without my backpack was a lot of trial by error and I… Full review

Sierra Designs Forty Winks

rated 4 of 5 stars Good well-rounded synthetic bag. Medium weight, medium packed size, medium warmth, and durable. This was my first sleeping bag I ever bought, purchased in 2001. I have been happy with the bag, and I think it is a good bag in all categories.  It is not a very lightweight bag, nor does it pack down very small, but it's a mid-priced synthetic bag and I think it is everything that it's supposed to be. Overall I've been pleased with it as a general purpose, well-built bag. Since then I almost always… Full review

CRAZO Premium Hooded Envelope Sleeping Bag

rated 4.5 of 5 stars This is a well-built envelope sleeping bag with mummy hood which is good for most three-season camping. The extra long and large size (86.6" x 31.5" ) assures comfort for adults even up to 6'11", and it allows you to use a liner or wear extra clothes to be warmer if it might get colder than the rating. As a retailer of this sleeping bag, I'd tested it several times with my friends before I placed the order. I have to say that I really love this sleeping bag. Honestly, I don’t like the narrowness… Full review

Deuter DreamLite 500

rated 2.5 of 5 stars A very cold sleeping bag, far out of its rating. This bag seemed like the perfect bag for my needs—a spring sleeping bag, highly compressible and lightweight, from a reliable tested brand. Unfortunately it fails in the only thing that really matters—warmth, big time. I used it while camping in a tent with a 15 mm E.V.A. mattress. I'll admit I'm a cold sleeper, but it has to be a night of 20+°C for it to be warm enough!!! And at those temperatures I can use a thermal liner that weighs a third… Full review

Kelty Tumbler 40/60

rated 5 of 5 stars This is a super nice product, keeps you warm and dry. Never slept so good in this. Great buy for the price too. Rolls up real easy also. This sleeping bag keeps a person warm, never had any drafts or cold spots. Easy to roll up and roll out. Not hard to get into like some others I have had. A lot of room inside for one person. My overall rating is a great deal for the money. Full review

Mountain Hardwear Lamina Z Spark 34°

rated 5 of 5 stars This is a great all-round three-season sleeping bag. It's comfort rated down to 34°f, and compresses really well. The outer shell is waterproof, and even though it is a mummy style sleeping bag there is plenty of room inside to move around and get comfortable. The Mountain Hardwear Lamina Z Spark sleeping bag is a 3-season sleeping bag that is comfort rated down to a temperature of 34°f/1°c.  I have used this on several trips with temperatures dropping as low as 3°c, and felt no chills at all… Full review

Outbound Lite Sleeping Bag -3°C

rated 2 of 5 stars Won't go back in its bag. Seems like a very good product. Used once so far. My problem with it is it won't go back in the bag it came in. I can't roll it small enough to get it in the bag it came in. I have tried several times and can't get it back in. Full review

Peregrine Saker 35

rated 4 of 5 stars This synthetic bag is very light and compressible and has some nice features for an extremely reasonable price point First off, I have absolutely no idea why it is so hard to find reviews on this bag. This bag really is a great synthetic option and I can't understand why there is such limited information about it! There is the constant battle of synthetic vs down. Weight vs comfort. How compressible is it vs. how durable it is and so on. Well personally I think the Peregrine Saker 35 is a solution… Full review

Marmot NanoWave 45

rated 3.5 of 5 stars Economical, compact, light summer bag. Purchased this bag in a regular size as it was all they had at the local store. Reg fits to 6'0" which is an inch shorter than me, but it's still a workable length. Small girth bag (60"/152cm), don't expect lots of room to move around in. Very tight to get in and out of.  I was in about 45°F/7°C temps overnight at 6,000'. With fleece pants and a long sleeved light shirt I was very comfortable. Not much loft, so the bag packs down very small and is very light… Full review
