Size: Reg

Just because you’re roughing it doesn’t mean you deserve a rough night’s sleep. Our Backcountry Bivy is a minimalist’s dream that maximizes comfort above all else. With interior space large enough to fit our revolutionary Backcountry Bed and a 2.5-inch inflatable pad on the inside, the Backcountry Bivy will have you snoring logs… even if you happen to be sleeping on one. Its waterproof shell and abrasion-resistant floor are seam-sealed together for extra protection in inclement weather and coated in PFC-free durable water repellent (DWR) for backup defense. The large opening, combined with our guy line design, adds headroom and overall comfort, and its equally large mesh window provides in-your-face views of the shining stars above.


  • Designed to fit our Backcountry Bed and sleeping pad 
  • Large U-shaped opening to make getting in and out easy 
  • Mesh window panel for ventilation in good weather 
  • Waterproof/breathable top fabric for increased comfort 
  • Fully taped seams (PFC free)
  • Guy line loop to increase peak height of bivy for increased comfort
