The award-winning Mobile Mummy 15 is a wearable, lightweight sleeping bag for the outdoorsperson who’s always cold and can’t sit still. Constructed with abrasion-resistant 20-denier nylon ripstop, treated with PFC-free durable water repellent (DWR), and insulated with our hydrophobic DriDown™, this versatile design brings a warm bed wherever you go, whether or not you’re ready to hit the hay. Just unzip the footbox and attach it to the toggles for instant walk mode around the campsite. Zipperless arm ports let you reach for the pot of coffee or stoke the fire and don’t cause uncomfortable pressure points in the middle of the night. Plus, a two-way zipper down the front center means easy entry and exit at all hours, giving new perspective to camping in comfort.

Features

  • 20-denier, partially recycled ripstop fabric (55% recycled) makes for a lightweight, durable bag that has less of an impact on the planet. The DWR C0 finish resists moisture and is PFC-Free
  • 800 Fill Power fluro-carbon free DriDown™ for lightweight warmth that is certified to the Responsible Down Standard (RDS)
  • Made for wearable comfort: the jacket hood moves with you when your roll around and turn your head. There are no cords or toggles to bug you.
  • Zipper-less arm ports are ready for instant use–simply stick your arms out to grab a book or hold a mug of hot chocolate. Unzip the bottom, stick your feet out and go for a walk while wearing the sleeping bag. Fasten the footbox up with toggles to prevent bag from dragging on the ground
  • Hood, zipper and arm ports all have reinforced draft tubes to prevent cold air from sneaking in
  • Long zipper runs down the center of the top of the bag and allows easy entry and exit; 2-way zipper lets you zip open the bottom for venting
  • Comes with stuff sack and mesh storage bag for easy pack up and convenient storage
