Sierra Designs Backcountry Bivy Sleeping Bag Blue/Yellow Regular. 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.
