[This review was collected as part of a promotion.] Great product alot smaller than the synthetic ksb double I have. Seems a little bigger that the original blue ksb down. But over all a great product.

Great 2-person sleeping bag that's light weight and surprisingly warm

This sleeping bag is very well thought out. It pairs well with the Klymit Double V insulated sleeping pad. I am 6'0" tall and it is more than long enough. The bag does seem a bit thin but it kept us very warm in cold conditions. The compression sac it comes with is great! I would recommend adding the Klymit storage bag to store it long term.

Soooo happy to have found

Soooo happy to have found a double sleeping bag! My boyfriend and I prefer to share a bag because I’m constantly cold, especially when we’re up in the mountains for some fall camping. The bag is warm and comfortable.

Warm & Fluffy!

Bought this right before a trip with my girlfriend to Red River Gorge. Knew the temp was going to dip and instead of using 2 separate sleeping bags I figured a 2-person bag would probably be better for warm. I was 100% right! Fluffy, cozy, warm down into 48 degree night and high quality materials made the weekend amazing! Puffed right up after about 10 min of laying this thing out on the double wide pad.

Bought this recently as part

Bought this recently as part of a gear-upgrade. As I've gotten married and had two kiddos (aged 2 years and 9 months), I needed to get a bigger tent / sleeping bag/ sleeping pad. Bought this along with the Klymit double sleeping pad which is sized the same and together they are absolutely great for my purposes. The bag / stuff-sack takes up about the same amount of space as a single bag and is pretty lightweight (I generally do 5-20 mile trips, 1-2 nights). The four of us fit in the bag snugly but with two 'normal' sized adults, there would be plenty of room. In terms of warmth, no complaints, I've stayed warm in it camping in central and northern California with weather in the high 30s/40s at night. My wife feels the same way and although my kids can't really articulate how cold they might be, their hands and feet have been warm when they slept in it and they actually slept all through the night the few times they have used it (which is more than can be said for their normal beds at home). There are zippers on both sides of the bag so either person can get out without disturbing the other which is a great feature. The best part is the fitted underside - think like fitted bedsheets. There is a little fitted bedsheet synched cloth sewn into the underside which hugs the sleeping pad and keeps the bag from sliding around in the middle of the night. The two work really well together.

I love this sleeping bag.

I love this sleeping bag. I am a big guy who is a fitful sleeper, constantly moving and rolling around. I also like to spread out when I sleep. This bag is soft, warm and spacious to accommodate my sleeping needs without making me feel constricted. It is also very easy to stow away despite its double size.
