The Roxy kept me warm in temp down to the low 20's upper 10's. I did get slightly cold around my middle, but nothing I couldn't deal with. I used a themarest womens air mattress, but have ordered the Big Agnes air mattress that fits the bag. The Big Agnes air mattress is also an inch thicker, which should help with the coldness I experience. Because of the way the bag is designed, the mattress doesn't slip out from under you. I like the fact that I can sleep on my side with ease. I like the little extra room in the bag without giving up warmth. I was able to pack it down to a small size using a compression bag, not the one it comes with. I am pleased with the warmth and the packability of this sleeping bag.
