Sierra Designs Backcountry Bivy, sized Regular. Never opened, still sealed inside plastic packaging. A MINIMALIST’S DREAM. 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, 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 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. Fully taped seams (pvc free). Compatible with most sleeping bags, especially the Backcountry Bed. Top Fabric:20D Nylon Ripstop WPB, DWR/10,400MM PeU, 18,300 g/day MVTR.
