A sleepwalker’s dream, the Mobile Mummy Sleeping Bag by Sierra Designs. If you’re a side or belly sleeper, roller, or one that has to get up throughout the night, the Mobile Mommy may be your new best friend. Unlike all the other mummy sleeping bags that restrict every moment or twitch, the Mobile Mummy moves when you do, in and out of the tent. Just like your down jacket hood, the Mobile Mummy provides a fitted comfortable hood using no cords or toggles, and moves when your head moves. Your arms are fee to move around by zipperless arm ports, but do contain a draft-prevention flap for when you need to keep warm. When nature calls and you need to take a stroll, the Stowable footbox unzips and clips to the back of the bag to prevent tripping and dragging. The Mobile Mummy sleeping bag is available in two, three, and four season comfort limits; and are all made with 20D Nylon Ripstop and Taffetta and 800 fill duck dridown.
