Sierra Designs Backcountry Bivy Tent - Just because you’re roughing it doesn’t mean you deserve a rough night’s sleep. Sierra Designs Backcountry Bivy is a minimalist’s dream that maximizes comfort above all else. With interior space large enough to fit Sierra Designs revolutionary Backcountry Bed and a 2.5-inch inflatable pad, the Backcountry Bivy will have you sawing 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 the guy line design, adds headroom and overall comfort, and its equally large mesh window provides in-your-face views of the shining stars above.
