Recent 3-Season Synthetic Sleeping Bag Reviews

Marmot Men's Trestles 15

rated 3.5 of 5 stars The bag is super warm, even on Mt. Whitney, and adequately warm when using in just a hammock. It is very bulky and does not compress as well as most other bags, but for a synthetic bag at a great price you can't complain too much. It kept me warm and dry and that's what is important. I wouldn't recommend it for long backpacking trips as it is much too bulky, but winter camping would be perfect. I used this bag on a week-long trip to Mt. Whitney and the bag was super warm sleeping in tents at 13,000+… Full review

ALPS Mountaineering Crescent Lake 20

rated 2.5 of 5 stars It's soft because it's bulky, but man is it bulky. I've had this sleeping bag for about a year, and it's the only one I've backpacked with since then. The reviews I had read suggested it was best for backpacking, but I think it is better for car camping. It's warm and has kept me warm in 28 degree nights in Tennessee. The regular size fits my 5'8" frame rather well, although sometimes there is too much room for cold air at my feet. Getting in and out of the bag is easy, and the zippers are insulated… Full review

Snugpak Jungle

rated 5 of 5 stars It's comfortable and light and keeps the critters off you. I love this bag! If I know it's not gonna rain I can just sleep on the ground or in a hammock with no issues. It packs small and takes up very little room. It dries quick and has plenty of room. It weighs almost nothing. I run hot and this bag was the perfect bag for me. I can take it anywhere with me due to its size and weight and I love that. If you don't winter camp this bag may be for you. Full review

Wiggy's Super Light

rated 5 of 5 stars I've used the 0 degree Superlight down to 6 degrees, and it worked as advertised. Two, maybe three foam pads down to this temperature. I've used the same bag with the overbag to -11°F, and once again, worked as advertised. If you stuff your wet gear by your feet, they'll be dry in the morning, and you'll have a ring of ice surrounding the outside of the bags footbox Full review

The North Face Men's Cat's Meow

rated 3.5 of 5 stars A solid synthetic bag that will treat you well in three seasons. I've always been intrigued by the Cat's Meow. It seems as though it has been a solid seller for North Face so I thought it must have a decent cost/performance ratio.  After having slept in it on a number of occasions now, I would say that It's a pretty decent bag. Many of the reviews on Trailspace are divided on the bag. It seems as though the older model gets a better review than the newer model. I have the older model.  Warmth:… Full review

REI Men's Lumen +25

rated 5 of 5 stars This is a great wet weather alternative to a down bag. It's very warm, the price is right, the weight is acceptable for a synthetic bag of this temp rating (sub 3 lbs), and the feature set is perfect-—not too many features, but ones that are useful. I highly recommend this bag for anyone that wants the warmth and packability of down, combined with the wet weather security of synthetic. *Reviewer note: I have the "regular" and "long" versions of this bag. This review is of the "regular" version… Full review

Teton Sports Tracker +5°F

rated 4.5 of 5 stars This is a great, comfortable bag. I have not used it in temps down to the 5 degree rating, but have found it to be a durable, easily packed, and comfortable bag for car camping and canoe camping, in nighttime temperatures from 30-50 degrees. It has some nice features, that make it a fine sleeping bag. I highly recommend this sleeping bag. I must disclose, I have not used this bag in its full, zipped up, mummy style mode, except for a trial. It is a very warm bag, and with our overnight camping trips… Full review

Big Agnes Hog Park 20°

rated 3.5 of 5 stars Great oversized bag. Being 6'4" and 230, love the size of the bag. Room for feet if you turn a lot. Warm for the temp. It is expensive. Full review

Kelty Tuck 20 / EN 22

rated 5 of 5 stars Warm, comfortable bag that performs as rated, with convenient features usually associated with more expensive gear. I paid $89 for the Kelty Tuck. At that price, I really wasn't expecting much. I do most of my camping in North Carolina, though, so even though I was spending two weeks in the Sangre de Cristo mountains of New Mexico, I really couldn't justify spending $200 for a 20-degree bag. So I bought cheap and prepared to suffer. So, first thing, the EN temperature rating is pretty accurate. Full review
