You'll never have to leave the cozy confines of your sleeping bag.
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 15°F, 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.

Choosing the Down Fill in your SD Bag
This video explains the difference in down fill and can be used to help pick your next Sierra Designs Bag. This is general information that can be used across all of our style bags.
I love my Sierra Designs Mobile Mummy Sleeping Bag. The Sierra Designs Mobile Mummy Sleeping Bag sets it self apart from other bags in the ingenous design with a snug head, ability to get your arms out without unzippinng the bag and the comfort of the materials is unmatched. My Sierra Designs Mobile Mummy Sleeping Bag has been down to 6 degrees farenheit with no super cold feeling. The Sierra Designs Mobile Mummy Sleeping Bag is rated to 15 degrees farenheit but it certainly can go below that, which is odd for sleeping bags as normally they are over rated. This Sierra Designs Mobile Mummy Sleeping Bag is underrated in my testing. They have a 2 season and a 3 season, mine is the 3 season. I love the Duck Dri Down used, it keeps you warm even when wet, which is the major flaw with normal untreated down and it is super warm! This bag heats up amazingly fast. Berz Rating: 98/100
