i have a hard time believing that this bag packs down to 7x7"
if it does i would buy it, but 7x7 and 7x15 is a huge difference.
are you sure its not a typo? it is misleading and should be taken care of if so.
I have not checked this one out but down bags can pack very small. My Lafuma bag that is the same temp fits in a stuff sack that I can squeeze down to a smaller size than 7x7 so if anything I would guess it takes up less space than 7x7inches.
