The innovative Sierra Designs Backcountry Bed 700 35 Degree zipperless sleeping bag lets you sleep in the great outdoors with similar comfort to your bed at home whether you’re a back, side or stomach sleeper. Featuring DriDown water-resistant down, this unique bag offers all condition performance for warm-weather backpacking.
Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel, and despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the bag’s 700-fill DriDown performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 10 times longer and dries 33% faster, should it become wet, than untreated down bags.
By eliminating zippers, Sierra Designs has created a sleeping bag that’s more similar to your down comforter at home than a traditional sleeping bag, though without your comforter’s annoying ability to shift off your body in the middle of the night as you move. Get in the Backcountry Bed through the unique catenary shaped opening that’s smaller than bag width to seal out drafts even when you’re shifting inside. Once settled in, the versatile integrated comforter fits naturally around you and conforms to your preferred sleeping position while also allowing you to easily adjust for varying temperatures. Insulated pockets in the comforter provide a cozy place for your arms and hands to stay warm if you’re not cocooned down inside the bag, or tuck the sides of the comforter around and beneath you when the temperature drops to be fully ensconced; the top of the bag also allows you to tuck your head inside for insulated warmth much like a hood. A stretch cord closure system allows you to completely seal out drafts. A unique zipperless, self-sealing foot vent allows you to extend your feet out of the bottom of the bag in balmy weather but effectively retains heat when temperatures require it. A sleeve on the bottom of the bag lets you pair it directly to a sleeping pad (pad not included) to even better create a bed-like sleeping experience while spending the night outside.
The Sierra Designs Backcountry Bed 700 35 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") sizes. A stuff sack and storage sack are included.

Real Customer Reviews
- Fan-freaking-tastic Backpacking Sleep Solution
Likes: Let's call it what it is, a solution. This isn't your dad's old sleeping bag. No. It's light-years from that. This is a generous portion of your bed from home brought with you into the front country or Backcountry.
I'm a stomach sleeper most of the time and have always loathed mummy sacks. This backcountry bed has finally solved my dilemma while retaining lightweight and small-enough packsize characteristics.
I bought a separate compression sack to really reduce the footprint of this bed but only use it when I really need to. Down doesn't like to be compressed.
Dislikes: I bought the standard regular size and didn't realize you can only use 20" wide pads with the slip. A real bummer. They need to allow up to 25" to really get comfortable.
