Sierra Designs Backcountry Bed 800 3-Season 15 Degree Sleeping Bag

Item #: 40280

Our Price: $399.95

Sleep in the wild like you do at home with a comforter. The Sierra Designs Backcountry Bed 800 3-Season Sleeping Bag is a zipperless sleeping bag that you enter via a large top opening. With an oversized, integrated comforter sealing the opening, you can sleep comfortably on your back, side or stomach. The oval opening is designed to naturally adjust in width to prevent cold drafts, yet it won't restrict your natural sleeping position.
  • 800 fill Duck DriDown - DriDown stays dry 10 times longer than untreated down, retains 2.7 times more loft than untreated down when exposed to moisture and humidity and dries 33% faster than untreated down
  • 20D nylon ripstop shell
  • 20D nylon taffeta liner
  • Zipperless Design - No additional hardware, cords or hook-and-loop closures to get in the way of a comfortable night of sleep
  • Catenary Shaped Opening - Opening is smaller than bag width so when you push out, the walls push in, sealing out drafts
  • Versatile Integrated Comforter - Wraps naturally to your preferred sleeping position and allows you to easily adjust to varying temperatures
  • Insulated Hand/Arm Pockets - Provides insulation under your arms when comforter is used outside of the bag
  • Sleeping Pad Sleeve - secures your sleeping pad to create an integrated "bed" sleeping experience

    Comments about Sierra Designs Backcountry Bed 800 3-Season 15 Degree Sleeping Bag:

    I brought the Sierra Design Backcountry Bed because it's the perfect replacement for my old synthetic mummy bag. With this bag I was able to cut out both weight and bulk from my exisiting list of backpacking gear. It has overall made my backpacking trip easier and more enjoyable. The built in sleeve for a sleeping pad means you won't wake up with the sleeping pad on top of you. I also liked that Sierra Design included a small slit on the botton of the bag to expose your feet if it gets too hot. I have comfortably slept with this bag on my sides and on my stomach inside a tent and it was very comfortable and kept me reasonably warm. The only downside I see with this sleeping bag is if you enjoy to spread your legs apart to sleep. Overall I have let my friend's test out my bag and they all wanted their own after they tried it out.

    It comes with it's own stuff stack, but I highly recommend that you purchase a compression bag to further reduce the pack size.
