Nice synthetic bag
Reviewed by Pat S. - August 28, 2018

Likes: Low price, comfortable, packs relatively small, relatively lightweight

Dislikes: Temperature rating is a little optimistic, bulky compared to down

Great Synthetic Sleeping bag
Reviewed by Brandon S. - April 1, 2018

Likes: Material, Weight, Not too clammy, Price. Large is long enough for somebody my size 6'5. Color. Great sleeping bag for alternative to down. Not to bulky like some other synthetic sleeping bags.

Dislikes: For a bigger person, the feet area can be kinda small. Find that to be a problem in a lot of sleeping bags.

Does the job over 35F with wind
Reviewed by supertreks - January 21, 2018

Likes: Not very warm But enough to stay well, with shelter, on the mountain at over 10,000 ft in height, with winds of 37mph and 38F.

Dislikes: - The zipper, it jams easily.
- A little heavy, but it's OK for it price.

Great sleeping bag for the price
Reviewed by Aaron L. - May 3, 2017

Likes: While I'm not sure how the temperature ratings work for these bags (I think a 25 degree rated sleeping bag means you should be able to be basically naked in this bag in your tent and be comfortable), I think 25 degrees is the coldest I would take this bag. I used this bag at about 32F while backpacking and I had socks, pants, and two long sleeve layers and a winter hat on and I was comfortable but on the lower spectrum of that. I always expect to wear layers at night so this wasn't a surprise or a disappointment. Maybe if I had the hood zipped all the way I would have been warmer, but I'm satisfied because I don't intend to use it in weather any colder than that (Mostly cold nights in Northern MN, 40s and 50s), so hopefully I''ll be okay when the warmer weather comes.

It also comes with a stuffsack and it's super easy to pack it back into and compress it down. I think it can be stuffed to about the size of a soccer ball? It's not insanely small. But the stuff sack does utilize a buckle and strap system, so it is ready to be attached to the outside of a backpack if necessary.

Dislikes: Nomenclature for backpacking equipment is a little loose, not sure I'd call any sleeping bag of this style "roomy," but there doesn't seem to be anything wrong with this bag. Not as fluffy as I would have expected, but it's not a high-end goose down bag, so you get what you pay for. This will work for awhile so I'm happy.

Effective low price sleeping bag.

Likes: Price. I got this bag on sale for a gift and it seems to be a winner. Under 3lbs and packs up pretty well for an economy starter bag.
