Outdoor Research: Alpine Bivy

Owning a full-feature bivy bag doesn't have to weigh down your pack or your budget. The Outdoor Research Alpine Bivy bag doesn't have the extra length or the airy foot vent found in the Outdoor Research Advanced Bivy Bag, but if weight matters in the backcountry, you won't mind missing seven extra ounces. Outdoor Research developed the Alpine Bivy bag with a deep taffeta floor that easily accommodates thicker insulated mats like the Exped Downmat 7. The shell material on the Alpine Bivy is a triple-ply GORE-TEX® Respirator+™, a special durable and waterproof fabric specifically created for bivy sleep systems by GORE-TEX® labs. GORE-TEX® Respirator+ optimizes weather protection while creating a vapor-permeable layer that won't collect condensation like other weather-resistant bivy systems. If you need more ventilation, the no-see-um netting on the Outdoor Research Advanced Bivy Bag allows better airflow without letting the bugs in. The Alpine Bivy Bag comes with five stake loops, a single hoop poles and a guy line loop for adding space in an incredibly lightweight, two-pound package. Inside you'll find a small internal mesh pocket for your watch, flashlight, paperback book, PSP or Game Boy DS game system (really…) and other evening essentials. The high-volume foot area gives you plenty of legroom, although some find there's also space to keep a few Nalgene water bottles from freezing overnight. If the dimensions seem a little cramped and you need the extra legroom, consider opting for the larger Advanced Bivy from Outdoor Research--you get everything here, plus more room and a cool foot vent.
