Sleep comfortably, even when it's 20° F outside, in the EDMBG Adult Mummy Sleeping Bag. With a polyester rip stop cover and polyester lining, it's designed to keep you warm from top to bottom while eliminating cold spots. The semi-sculpted hood surrounds your head to keep you warm. A special quilting construction eliminates potential cold spots. The Velcro closure at the neck ensures the bag stays in place to keep you warm while you toss and turn. If the bag gets wet no problem, use the easy hang hooks to dry then easily stuff it in the carry bag when you're ready to move onto the next adventure!
