I LOVE this bag!! We do alot of overnights out and this is the first bag that warms fast and holds ALL night. The body is wide enough to curl up sideways, even bend a single knee with no restriction. I love that is is super light, but that also comes with tear easy, I wish it were a touch tougher but the zipper is guarded and I think it is made to last...you won't regret this one!!

i have never had a bag that i did not give myself at least an extra 20 cushion when packing...until this one. the window in which this bag is comfortable is huge. it packs so small. i am finally saving the solarflare for true arctic cold and using this for winter trips. if i were buying one bag and were a four season camper this would be the one!

My main purpose of buying this bag was to fit it in my 24L pack. And boy does it compact well. Fits in my size M (went up a size so it was less like a hot dog and more like a hamburger) Sea to Summit dry compression sack. Does exactly what i got it for. It takes it less than a minute to expand to it's full loft. And it's incredibly cozy to boot.

As far as actually being a zero degree. I never think they're warm enough. But when compared to a comparable synthetic it outshines it by at least 10 degrees. I just matching my bag with an insert.

Oh yes and the yellow on the outside doesn't match the shade of yellow on the inside (w/ the blue). Doesn't bother me.. but some might find that odd. Also has a amount of writing on the side (more at least than was shown in the picture).

Highly recommended bag.

This bag is awesome. I bought it for backcountry skiing hut trips and winter camping (as I froze in my 20 degree bag last February in Moab) and it has proven worth every dollar. Plus, the girlie side of me likes the butter yellow and baby blue colors, too. It really is light, stuffs down to a tiny size, and the stuff sack has convenient straps for hanging it off your pack. I absolutely recommend this bag.
