Recent 3-Season Synthetic Sleeping Bag Reviews

The North Face Elkhorn

rated 5 of 5 stars Great bag. Warm, durable, and priced reasonably. I bought this bag new from a BPS store in 2010. I still have it, and it's still in good condition which is a testament to its durability. It has gotten dirty, but never ripped or had another significant problem.  All in all I love this bag. It's my go-to winter camping bag. (My other bag is a Kelty Cosmic 21.) My wife has a Marmot Trestles 0 bag and I wouldn't trade her. The Trestles bag is nice, don't get me wrong, but even in the compression sack… Full review

Therm-a-Rest Saros

rated 2.5 of 5 stars I got this bag for an AT section hike. It was very comfortable at first and worked well with the Therm-a-Rest Prolite Plus. I did find it irritating that the bag was so warm that most nights I could not sleep in it zipped up. The zip did not go all the way down to feet. Zipper broke and that was that. Backless weight saving idea not so sure about either, made it hard to use independently without the sleeping pad. I am getting a replacement sent from the company, the Capella women's bag. We will… Full review

Mountain Hardwear Laminina Z Flame

rated 4 of 5 stars If you can afford just one bag, and need a bag that "does most" — consider the Lamina/Lamina Z Flame. While this bag is not for gram-weenies, it is a great mid-range, mid-cost bag that hits a really great sweet spot for wet and 3-season use. This bag also has among the most features, lowest cost, and warmth rating in its class. Overall Specs The unisex version of the Lamina Z Flame bag is rated down to 22 degrees Fahrenheit for the EN lower limit and 32 degrees Fahrenheit for the EN comfort… Full review

Moonstone Optima

rated 3 of 5 stars I was cold at Camp Verde, AZ, campground in February and the zipper snagged the nylon backing. Good for spring camping in dry weather at Havasupai Falls Campground with no tent. I decided to take advantage of a late winter snow fall one February and skied at the Flagstaff Sno-bowl. I drove to a Camp Verde camp ground that night and would sleep in the back of my S.U.V. I found myself so cold that I was starting the engine frequently to heat up the truck. At some point the zipper snagged the backing… Full review

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
