Recent 3-Season Synthetic Sleeping Bag Reviews

Kelty Tuck 20 / EN 22

rated 4 of 5 stars Great bag at a great price. Just received it. I also own the Kelty Mistral 20 degree bag. The Tuck is 11 ounces lighter, and compresses to fit in a Kelty medium compression sack. The Mistral compresses down to fit in a large compression sack. The Tuck is listed as a 22 degree bag, not a 20. Has a zipper about six inches from the end of the bag—with the zipper open, you can have your feet out of and on top of the bag. Full review

Eureka! Women's Casper 15

rated 2 of 5 stars If you're a tallish or largish woman like me (5'8", size XL), you probably won't fit inside. I bought this for backpacking, as it is fairly small and light, but it didn't work for me. I couldn't fit in this bag. Granted, I'm 5'8", so at the upper limit of their height range, but sticking out the end wasn't the only problem. I wear a women's XL, so I'm definitely bigger, but still within straight clothing sizes...but I couldn't zip it up with my arms inside. I was cold as expected, but it was way… Full review

REI Nooksack UL +10

rated 3.5 of 5 stars For a 10°F synthetic bag, it packs down very well (8.5 x 11), it's comfortable, and zips well. From my experience it's not a 10°F bag. I was cold in this bag at 40°F with thermals on. This is one of the most inaccurate bag ratings I've tested out of dozens. If the bag read 35°F I would consider this a great bag. Everything about the bag is positive but I would feel terrible if someone actually depended on this bag in 20-30's°.  If you buy this bag as a summer bag, I think you will be very… Full review

REI Shasta +15

rated 2 of 5 stars Though the bag is made of quality materials, it does not pack down well and lets out heat around the collar. The bag is a decent car camping summer bag but does not do well in cooler weather. I tested it last night (low 36°F). Since the bag had a 15° rating, I figured comfort rating would be somewhere around 30°. I cinched the hood and collar until there was only a 4" diameter circle. There's not really a collar to cinch. The draft tube extends from the side of the bag in one continuous run that… Full review

Mountain Hardwear Men's Lamina 20°

rated 4 of 5 stars Is my go-to bag for a couple of seasons now for some good reasons... but the ZIPPER! I have a love/hate relationship with this bag. It has been my favorite synthetic bag I've owned. It presses down to 8 x 10. It's super silky comfortable. It has a great shape. The collar holds heat well. the compression sack is a really nice 3 strap/1clip design so you can unclip one strap and pull the lid back. The bag has a small pocket.  The zipper sticks HORRIBLY! Every 3-5 inches it sticks if you are trying… Full review

Alpine Design 20 Degree Sleeping Bag

rated 1.5 of 5 stars Don't buy this. The stuffing rips out easily and the zipper broke just after a few months in light use. Without the zipper the bag is useless. They need to put more money into the zipper! Don't buy. Full review

Wiggy's Sleeping Bag

rated 2 of 5 stars Military style robustness, but not up to its temperature rating. I had the flexible temperature range sleeping system: i.e. two bags that are made to fit into each other (the outer bag has an additional zipper to mate with the zip of the inner bag). The idea of a sleeping system was the reason I bought the bags. The inner bag was supposed to be warm down to -15°C or so: i froze my ass of around 0°C. The combination of both is rated -40°C (=-40°F). I quit a trip in -15°C, because it wouldn't… Full review

Marmot Men's Trestles 15

rated 4 of 5 stars At entry-level price and above entry-level quality, this is an excellent 3-season bag that can withstand mild winter temps. It's just not very lightweight at 4 lbs. Conditions: I bought this bag nearly five years ago because of an increased interest I was taking in colder weather trips and my Marmot Alpine 40 Minimalist wasn’t cutting it for lower temps. However, I liked my previous Marmot bag, so I stayed with the brand (and price range) instead of going all-in on a down bag. Someday I hope… Full review

Wiggy's Hunter Super Lt

rated 5 of 5 stars Very well constructed and warm! I purchased the Hunter Super Lt with hood rectangular, the ftrss system. I highly recommend this bag. I use it for base camps. I have not used the outer bag for hiking, but might since it is light. I recommend this product for anyone who wants a quality sleeping bag made in the USA that will last a lifetime. Customer service was fantastic. The web site spells out the return policy. The invoice also spells out the return policy — no issues at all. Answered all my… Full review
