Bought this bag in college about 13 yrs ago; best money I've ever spent, and I've spent a lot of it ;) This bag is absolutely bullet-proof and warm as can be, plus it compresses to the size of a volleyball. I use mine in all manner of temperatures, even when sleeping indoors; just don't zip it up. At some point I felt like the loft was going down a bit, but I just used it this weekend and it's fluffy as ever. I can't imagine a better sleeping bag.
Some mentioned problems compressing the DryLoft version. Just zip it inside out before you stuff it; problem solved. Of course if you do that, don't drop it in the river ...
