Sierra Designs - Mobile Mummy 600 3 Season

The Mobile Mummy 600 3 Season from Sierra Designs is a down-filled sleeping bag that you can wear like a garment to sit up, or stow the footbox to walk around camp. Great for ultralight backpackers who don't want to carry both a sleeping bag and a puffy jacket.

The 58" zipper is easier and more natural to operate. Dual sliders can be zipped from the bottom for venting

Don't Fear the Wet
