I picked this up with a 30% off coupon, and sadly that is probably the only way I would buy this bag again. I am 5"10' and ordered the "Long" since I didn't want to be cramped. This bag is fantastic, it doesn't hug the body as much as I thought, but the stretchiness is nice for sitting cross-legged during breakfast, plus with the cinch at the bottom I can make the bag a bit shorter. Perfect for those who can't do the mummy bag thing and need to sleep with their knees raised. I don't know if 25 degrees is really accurate. I slept in about 35 degrees and did wake up a little cold, I was wearing a long sleeved top and boxers, so maybe pick up some thermals. I did add a polyester liner and that kept me much warmer, defiantly rated to 25 degrees with a liner.
Despite what I heard the Long doesn't pack up to the size of a Nalgene bottle, more like the size of a Dura-Flame log. All in all, I really like this bag, but I wouldn't pay full price.
