  • Climb into the bag via the large oval opening on top; the oversize comforter seals up the opening so you can sleep comfortably no matter your position: back, side or stomach
  • With a European Norm (EN) lower-limit rating of 29°F, the Backcountry Bed 800 2 -Season sleeping bag is suitable for spring and summer backpacking
  • On warmer nights, flip the comforter outside the sleeping bag and tuck it back for ventilation; insulated hand/arm pockets provide warmth when the comforter is outside the bag
  • Down is considered the best insulation available but when wet, it quickly loses loft and the ability to keep you warm; 800-fill-power DriDown is treated to resist moisture
  • Proprietary process treats each individual duck down plume with a molecular-level polymer so the down stays dry longer, lofts better and dries faster than untreated down
  • DriDown insulation stays dry 10 times longer, retains 170% more loft when exposed to moisture and dries 33% faster than untreated down
  • Ripstop polyester exterior endures frequent use in the outdoors; polyester taffeta lining is soft and comfortable next to skin
  • Sleeping pad sleeve on the bottom of the bag secures your pad (pad sold separately) to create the experience of a fully integrated bed
  • Sierra Designs Backcountry Bed 800 2-Season Sleeping Bag comes with a stuff sack and storage sack
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
