"The lack of insulation on the bottom drives a side sleeper nuts!"
I ordered the petite, at 5'4", and really struggle with how short it is. When I wiggle my toes, it pulls the hood down over my eyes. I am a side sleeper and it is not insulated on the bottom of the bag and this drives me insane. There is a sleeve for you to slide your sleeping pad into the bag but my sleeping pad was too big. When I borrowed a friend's pad and would toss and turn, I would no longer be sleeping on the pad. It would be stuck to my back, not cushioning me from the ground or keeping my back warm. If the back was on the ground, my face was mashed into the hood. Ugh. All the other reviews swore that it was a great bag but they must not move around when they sleep.
