Outdoor Research Advanced Bivy Sack

The Outdoor Research Advanced bivy sack has a commodious design, featuring a generous footprint for those who prefer a little more wiggle room . This waterproof, breathable bivy sack has two poles to keep overhead material off your face for a less confined feeling. Three-layer Gore-Tex® Respiration Positive™ laminate fabric was created just for sleep systems—it's both vapor- and gas-permeable. Durable and waterproof Hydroseal® coated nylon floor; fully taped seams ensure waterproof protection. Two shockcorded Delrin® poles allow the bivy to open in several different positions from wide open to awning style. Removable, tightly woven no-see-um mesh provides lightweight, chemical-free bug protection that doesn't interfere with visibility. End-opening zipper with a wide storm flap allows easy entry and exit without sacrificing waterproofness. Footprint is now sized to fit thick sleeping pads for increased comfort. High-volume foot section with zippered vent allows sleeping bag to maintain full loft for optimal warmth around feet. Zippered interior mesh pocket holds eyeglasses or other small items for easy access. Five stake loops and three guyline loops provide ample anchor points.
