    Be the envy of your camping buddies.

    If you dread those mornings at camp when it's too cold to leave your warm sleeping bag, then the Sierra Designs Women's Mobile Mummy 800 Sleeping Bag is for you. Like many down mummy bags, this bag is light enough for backpacking trips and warm enough for temperatures as low as 15°F. Stuffed with 800-fill duck down insulation, this lightweight bag has an excellent warmth-to-weight ratio, and its stuffs into a small corner of your pack so you can easily bring it anywhere. Unlike most down bags, however, Sierra Designs added its proprietary DriDown treatment to the down for water-resistant protection if you're camping in wet environments. And unlike most mummy bags, the Mobile's unique design includes a women-specific fit that allows you to sleep on your side and stomach as well as your back.

    Let's get back to those cold mornings. Instead of getting out of your bag to shiver your buns off, you can push your arms through the zipperless armports, slide your feet through the center, two-way zipper, and then attach the footbox to the bag just above your knees and walk around the campsite with the same wonderful warmth you slept in. When you're up and about in this bag, its design makes sure the bag rests on your shoulders like a jacket instead of resting uncomfortably on the hood. Sierra Designs reinforced the hood, zipper, armports, and draft curtains to prevent any cold-air drafts from seeping in while you sleep.

    • Familiarity: I've used it several times

    I've used it with a hammock, instead of a tent. First time was at Sequoia NF at 7000' elevation. Night temps dropped to 42 farenheit. My feet were freezing and there were cold spots on my upper back.

    I learned from this and on my Yellowstone/Grand Tetons NP trip, I made changes. I used a fleece bag liner, but placed it between the hammock and the bag. I placed a rain jacket over the foot section of the bag. At 40 degrees down to 34, I was pretty toasty. Even with a drizzle, the bag got wet, but not drenched. It dried quickly and was ready for another night.

    I love that I can stick my arms out and not have to unzip when it's cold. The hood is perfect...super comfy fit. I'm 5' 4


    One of the best!

    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
