Manufacturer's Description

Offering a fresh and improved take on the classic mummy-style sleeping bag, the fully-featured Sierra Designs Mobile Mummy 800 is designed to fit more like a garment and move with you so you can sleep on your back, side, or stomach without feeling constrained or suffocated.  

Zipperless armports allow you to use your hands while fully zipped into this bag, so you can cook, read, and more without getting out of your sleeping bag.  For added mobility, a stowable footbox can be tucked up and toggled, allowing you to walk around.  A centered, front zipper is easier and more natural to operate while dual zipper sliders allow venting from the top or bottom.

A jacket-style hood and garment-style shoulders give a natural fit, creating a more comfortable bag that moves with you while you sleep, sit up, or walk around.  800-fill DriDown insulation is light, compressible, and warm, even in damp, humid conditions.
