Recent 3-Season Synthetic Sleeping Bag Reviews

Mountain Hardwear HyperLamina Flame 20

rated 4 of 5 stars I purchased this bag for sea kayaking in the NW. This bag is warm, compresses small for a synthetic filled bag, and has a roomy footbox and a relaxed mummy design. First off, I have used this bag on multiple trips, both backpacking, sea kayaking, and car camping. I feel I have used it enough to give a solid review of its features. This bag is light enough to carry and compresses small for a synthetic bag. It has no noticeable cold spots. The baffles seem to hold the fill in place well. The best… Full review

Wiggy's Sleeping Bag

rated 1 of 5 stars Just got off the phone with Jerry with a problem with a 0-degree bag not keeping me warm in 35-degree weather,  So asked what he suggested, to my surprise no help with possibility of a problem with the bag. His fix was buy fishnet long underwear for 80 dollars. Too funny! OK, I will use this bag for my dog to sleep on and go buy a good bag. Full review

Mountain Hardwear UltraLamina 0°

rated 5 of 5 stars The bag is warm, packable, and good quality. Someone who sleeps cold should do well in this bag. This is the best sleeping bag I've used so far. Using it recently on the AT it kept me warm @ 20°F and got too hot when I zipped it up the second night @27°F in the tent. I have a feeling it will go down to 0°F, but it works well into the teens. Have the regular size so there is extra room all over the bag for me to move around in. I probably should have a short, but the extra room allows me to store… Full review

Marmot Men's Trestles 30

rated 3 of 5 stars Gone are the days when Marmot made durable and hardcore outdoor products. Instead, we now have Marmot, the maker of average to subpar outdoor products that are at best just a step ahead of Walmart quality. The Trestles 30 is suitable for car camping and campground only outings. While I cannot say the Trestles 30 is a "bad" bag, I also can't say this is a bag that is going to do anything more than be a decent bag for car camping and front country endeavors. Like other Marmot products I have tested… Full review

Mountain Hardwear Pinole 20°

rated 4.5 of 5 stars Warm cozy and bulky synthetic sleeping bag that weighs almost as little as a down sleeping bag. Excellent quality and features. I used this sleeping bag while hiking for two months the Israeli National Trail and I did like it a lot. I'm a very cold sleeper, with a slim fit, which means finding a good sleeping bag is a nightmare for me, but I did find this bag warm with no cold spots, which was a nice surprise. I used it in freezing desert nights and misty damp nights, and while most of the other… Full review

ALPS Mountaineering Crescent Lake 0

rated 3 of 5 stars Nice bag. Light but extremely bulky. Took this bag on a 10-day float on the Green River. Needed to buy a 35 L dry bag to replace the stuff sack as it took way too much space in my pack. Temperatures dropped to mid forties and the bag was very comfortable. The bag had no cold spots or drafts and fit perfectly. The bag doesn't compress well and is too bulky.  Full review

The North Face Squall

rated 4 of 5 stars Lightweight, synthetic mummy bag with 20 degree rating. I picked up this bag on a closeout sale for around $75. Especially for the price, it has really been a good investment. I've used it in below-freezing temps, as well as the summer. It gets a little too warm in the summer, but otherwise it has done everything I've asked of it. I've had it since 2003, and it still looks brand new. It is machine washable, and all seams and zippers hold up well against wear and tear. I'm a 5'4" female, so I have… Full review

Mountainsmith Crestone 0

rated 2 of 5 stars Should not be rated 0 degree Fahrenheit. Maybe 0 degree Celsius, because it may keep you alive at that temp if you wear some warm clothes with the bag, but even at 40 degree Fahrenheit it would not keep me warm with several layers on.  Full review

Marmot Men's Trestles 15

rated 4.5 of 5 stars Great bag from a great company at an even better price. Bought one for myself last fall. I got about seven trips in it so far, all on the AT or Mountains-to-Sea Trail in East Tennessee and Western North Carolina. The coldest night so far was 25 degrees and I had no issues with getting cold. You can get bags that compress smaller and weigh less, but not for 104$. The zippers can be a pain as most previous reviewers noted, however I think I have figured this out just through trial and error. Leave… Full review
