    1. Customer Review

      I just bought this bag two days ago. I'm indigent and sleep outdoors. Upon opening the bag I found that there is a hole,(design defect), where the zipper starts at the base of the bag. The hole is about two inches across, and I could fit my enitre finger in it, if not two fingers. My feet were chilled throughout the night; it was totally dismaying. How could the designer miss this particular feature? The product description boasts that the bag has a draft tube that keeps out cold air and prevents heat loss! The designer and manufacturer must have had some sort of error communication-wise. What is the bag for, a liner to a different bag that is more costly? What a swindle! -C. Miller on Dec 12th 2013
