Used this bag for 3 night in Ouray, CO where it was about 35 every night and stayed very warm. I just slept in long johns and had to take my socks off because I was getting too hot. I have a long so at 6'2", 225 the long provided the extra room I needed. I have a an earlier version of this bag and they improved the zipper on this model greatly. It's much bigger and rarely gets snagged like my old one, the draft tubes are also a little bigger which seals the heat in. Overall, great basic bag, might be too big back packing but the down would be perfect.

FYI, mine came with a stuff sack.

I bought this for my wife and bought myself the down version since i like to backpack and she doesnt. This bag is not for backpacking in my opinion..its large over twice as big as the down version and weighs quite a bit more. My wife who is always cold was warm in this but i have no idea how cold it was at night...maybe 40 degrees. For 80$ or so this is a great bag. I boght the long version ofndown bag for 110$ so for anlittle more you can save space and wieght but i think each bag performs well and equally

Great bag for the money. I replaced a 30 year old North Face bag with this one. It's on the thinner side and I doubt it will be comfy at a true 20 degrees. But I'm planning to use a silk/fleece liner inside to warm it up.

Used twice already and worked great. It kept me warm on a trip that got into the 40s at night, but was not uncomfortable on a trip that was in the high 50s. The extra long size is very long -- my boyfriend has the same sleeping bag in normal length and fits fine at 6'4".

Was able to use this for my camping weekend recently. While the zipper does not zip all the way down and that can be annoying it's not a huge deal. I slept in a tent with just a pair of yoga pants and a t-shirt in 55 degree weather with no issues at all. I also hung out with it in my hammock. Kept me nice and warm and didn't feel any wind through it. Love it!

Picked this up as a Warehouse Deal for less than $60. Camped this weekend in Iowa with lows at night hovering around 35 degrees. At night, dressed only in jeans and a button down shirt, I awoke in the morning feeling very warm and rested. I think I'll pick up a sleeping pad or a thermarest pillow to compliment this great bag. I pack a 48 liter Osprey, which this bag fits into without any issue -- however the bag runs a little large. Still not an issue as I mostly car camp. Overall, great bag and worth the price.

I have other synthetic fill sleeping bags but this one quickly became my favorite for general purpose use. It's warm enough to satisfy most of my camping needs and it's very comfortable. Very packable as well.

This is not a backpacking sleeping bag. It would be a nice sleeping bag for car camping though. Doesn't come with a compression bag, and doesn't compress well at all.
