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.

You greet those chilly mornings while you're camping like a mummy coming out of a coffin, as slow as death itself. But instead of dirty toilet paper wrapped around you, you have the Sierra Designs Mobile Mummy 800 Sleeping Bag keeping you nice and toasty while you make breakfast. All you need to do is push your arms through the zipperless armports and slide your feet through the center-two way zipper. Then attach the footbox to the bag just above your knees so it doesn't drag on the ground while you walk around. You don't have to worry about cold drafts seeping through the zipperless armports while you're sleeping because they prevent air from coming in and out. Stuffed with 800-fill duck down insulation, this bag is light enough for backpacking trips and warm enough for temperatures as low as 15F, and Sierra Designs added its proprietary DriDown treatment to the down for water-resistant protection that helps keep you dry if it's misting out as you're making breakfast all bundled up. The Mobile Mummy's unique design also lets you sleep on your side and stomach as well as your back. Sierra Designs made the shell out of ripstop for durability that remains lightweight, and the liner out of taffeta to keep you nice and cozy all night long. When you're up and about in this bag, its design makes sure the bag rests on your shoulders like a jacket instead of falling uncomfortably on your head.
