Query: very nice

This sleeping bag is great! VERY puffy and comfy so it doesn't even feel like you're laying on the floor. the zipper plow thing is the most genius thing ever!! the zipper runs smoothly and never gets caught. the coolest part of this sleeping bag is the little velcro pocket near the top, it's perfect for holding my mp3 player. very warm and cuddley, I love it.
