Mummy knows best - resurrecting ultimate comfort. The award-winning Mobile Mummy is a wearable sleeping bag for the cold person who just can't sit still. While most sleeping bags are just for sleeping, this one is ready to do it all. As you're sleeping, it follows your every move, whether you're on your side, back or front. It's more like an outfit, with the zipper down the center front, armholes at either side and a footbox that can be tucked away so you can walk around camp making dinner. Sit up, read a book, enjoy a cup of coffee, all while bringing your bed along for extra warmth. 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(TM) 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 Materials Liner Fabric: 20 denier recycled nylon Shell Fabric: 20 denier recycled nylon Insulation: 800 Fill Allied DriDown Tech Specs REGULAR EN Limit Rating: 16.0deg F / -9.0deg C EN Comfort Rating: 27.0 deg F / -3.0 deg C Fill Weight: 18.56 oz / 525.0 g Weight: 2 lb 6.5 oz / 1.09 kg Fits To: 72.0" / 183.0 cm Length: 78.0" / 198.0 cm Shoulder Circumference: 60.0" / 147.0 cm Hip Circumference: 58.0" / 147.0 cm Foot Circumference: 40.0" / 102.0 cm Stuff Sack Size: 8" x 16" / 20.3 x 40.6 cm LONG EN Limit Rating: 16.0deg F / -9.0deg C EN Comfort Rating: 27.0 deg F / -3.0 deg C Fill Weight: 20.8 oz / 590.0 g Fits To: 78.0" / 198.0 cm Length: 84.0" / 213.0 cm Shoulder Circumference: 62.0" / 152.0 cm Hip Circumference: 60.0" / 152.0 cm Foot Circumference: 42.0" / 107.0 cm Stuff Sack Size: 8" x 16" / 20.3 x 40.6 cm | Sierra Designs Mobile Mummy 15deg, Size Long
