The Sierra Designs Mobile Mummy 800F 2 Season Sleeping Bag was designed to move when you move so that you can sleep on your side, stomach or back and never feel constrained or suffocated. You can wear it like a garment and can sit up and use your hands to drink a hot beverage, cook or read. Or stow the foot box and take a cozy walk around camp.
  • Ultralight jacket hood with no cords or toggles - Fits comfortably snug around your face like the hood on a jacket so it moves with you
  • Zipperless armports - Armports are ready for instantaneous use - no zippers, toggles or hook-and-loop closures to get in the way, self seal when you pull your arms inside
  • Garment-style shoulder design - Tapered to rest on your shoulders - not your head - when you're upright in the bag
  • Centrally placed, ventable zipper - The 58 inch zipper is easier and more natural to operate, with dual sliders so it can be zipped from the bottom for venting
  • Draft prevention - The hood, zipper, armports, draft collar, draft tube, and draft curtains are all reinforced with additional interior down baffling to prevent cold air drafts
  • Stowable footbox - Footbox can be tucked up with toggles to prevent the bag from dragging you are walking around. Perfect for those nighttime trips to relieve yourself.
