Recent 3-Season Synthetic Sleeping Bag Reviews

Wilderness Experience Latok 1

rated 5 of 5 stars Purchased the Latok as my first mountaineering bag in 1981 and I still use it today (2018). It has saved me from peril on more than one occasion, also I've slept directly on snow in this bag and was completely comfortable! It's kept in near perfect condition. The quality of Wilderness Experience products are second to none. I grew up in Central Oregon in a little town named Bend. In 1981 I got my first job at Discount Mountain Supply where I worked and spent every penny I made...on Wilderness Experience… Full review

The North Face Snowshoe 3D

rated 2 of 5 stars This bag was rated at zero degrees. The fill is inadequate and to top it off there is no draft collar. I would rate it as lame 40-degree bag. Full review

Mountain Hardwear Men's Bozeman Torch 0

rated 4.5 of 5 stars BIG BANG FOR THE BUCK! HIGH END FEATURES for a low-priced, quality, 0 degree bag. Great whether backpacking or car camping. Cool night comfort in a fairly light, synthetic bag. Proper dimensions for a regular length bag—not too tight or too loose, with two drawstrings for colder nights. Big bang for your buck! After some seriously thorough searching, I bought a Torch for a great sale price. There is simply no other QUALITY brand bag I could find with what this one has to offer, for near the price. Full review

Teton Sports Tracker +5°F

rated 3.5 of 5 stars Nice for the price. Not a 5-degree bag. Long is not long. Long is not long. At 5' 8" and chubby, I fit snugly. I can't see anyone over 6 feet fitting in the LONG bag. Zipper sticks at the top when closing; opening was easy. Used several times in the low 20s and started feeling chilly. Not a 5-degree bag; I don't think it would be good below 20 degrees without a liner or extra clothes. Drawstring on the hood worked well; felt no air leaks along zipper. Pocket inside by chest is too small for glasses… Full review

The North Face Elkhorn

rated 3.5 of 5 stars This sleeping bag is one of the best designs that I've ever slept in. It comes close to the comfort rating if you wear some insulated clothing to sleep. It's a bit bulky and its weight works against it. Warmth: The bag has a 0°F (-18°C) rating. Normally, that rating is the lower end rating that identifies the temperature at which the bag will keep you alive. As a general rule, I add 15°F (9.5°C) to that rating to provide a temperature "comfort" rating. According to those parameters, you should… Full review

Mountain Hardwear Pinole 20°

rated 3 of 5 stars Decent bag with some concerns. I bought this bag because I wanted something a little smaller. Sacrificing warmth I went for a three-season bag with the option of adding a liner. If in higher elevations, as I usually am, some long johns and merino were enough to keep me toasty. My only issues are the zipper must be carefully opened and closed so as to not get caught, which it is prone to do. The hood system is simple and effective, but being a spinner when I sleep I tend not to use it or else I get… Full review

Teton Sports TrailHead +20F Ultralight

rated 4 of 5 stars Men need more shoulder width. This is a well engineered bag! It's comfy with plenty of room at the head and foot box. However, its width of 32 inches is too small for amMan 5'10"+. I couldn't relax having such a confinement at my chest and shoulders, making me feel that I was putting too much stress on the bag. While in 30 Degree F. temps, the bag performed well. I was warm and not overheated, but my feet were chilled. Doubling my socks remedied this dilemma. I would highly recommend the Trailhead… Full review

REI Men's Lumen +25

rated 4 of 5 stars Comfortable, long lasting three-season sleeping bag. Purchased in 2012 when I first got into backpacking. Wanted an affordable bag for backpacking. Packs down (with aid of a compression sack) to about the size of a basketball. Relatively heavy, but very warm and cozy.  Have used a lot in five years and it's held up great. Eventually would like to upgrade to a lightweight down, but for the money, it's hard to beat this bag. Full review

Marmot Trestles 20 Semi Rec

rated 4 of 5 stars After doing some research, I wanted a bag that was synthetic and wasn't a tight fitting mummy bag. This fits the bill. The double zippers are great and allow the bag to breathe on hot nights. I've never been cold with this bag, even when the temperate outside dips into the 20s. I have found that in that range, the bag does take sometime to warm up inside. As everyone else has said, the zippers do tend to get caught on the fabric a lot. The glow-in-the dark zipper finders are also pretty weak too. Full review
