Sierra Designs

Features

1. Catenary shaped opening is smaller than bag width so when you push out, the walls push in to seal out drafts
2. Integrated comforter wraps naturally around your preferred sleeping position and moves with you, thanks to hand pockets of either side of the comforter
3. Zipperless design cuts down on weight
4. With no insulation on the underside of the bag, the integrated sleeping pad sleeve secures a sleeping pad to the bag, letting the pad provide the warmth
5. Water-resistant 850-fil duck Dridown dries fast should it get wet; nylon ripstop shell is tear resistant
6. Innovative zipperless foot vent self seals closed and can be operated from the inside using only your feet
7. Insulated hand/arm pockets provide insulation under your arms when comforter is used outside of the bag
