Recent 3-Season Synthetic Sleeping Bag Reviews

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 impressed.

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

ALPS Mountaineering Unisex Desert Pine 20

rated 4.5 of 5 stars A solid and affordable starter bag that performs ably. Full disclosure: I've had mine for closing on five years now. Take this review both as a testament to its performance and durability. Keep in mind that the model of bag may have changed for the better or worse since I bought mine. ALPS products are, overall, pretty solid offerings in the entry to mid-grade market. They're not as light, compact, or elegant as some of the competition with fancy brand names. They are, however, performing, durable,… Full review
