Product Information


Sleep in the wild like you do at home with a comforter. The Backcountry Bed SYN is a synthetic-insulated, zipperless sleeping bag that you enter via a large opening in the top. With an oversized, integrated comforter sealing the opening, you can sleep comfortably and naturally on your back, side, or stomach. The oval opening is designed to intuitively adjust in width to prevent cold drafts, yet it won't restrict your natural sleeping position.


  • The catenary shaped opening is smaller than bag width so when you push out, the walls push in to seal out drafts.
  • A zipperless design means not additional hardwear, cords, or Velcro to get in the way of a comfortable night's sleep.
  • Sleeping pad sleeve secures your sleeping pad to creat the experience of a fully integrated bed.
  • Hands-free zipperless foot vent self-seals and can be operated from the inside using only your feet to easily adjust to varying temperatures.
  • Insulated hand/arm pockets provide insulation under your arms when comforter is used outside of the bag.
  • Versatile integrated comforter wraps naturally to your preferred sleeping position and allows you to easily adjust to varying temperatures.
