Black Diamond's Big Wall Bivy is a super light, hooped bivy designed for climbers. Bibler's hoop is a Delrin rod sewn into the sack, so there is nothing to set up and no parts to lose. Made of the same waterproof and breathable ToddTex laminate as used in all Bibler Tents, these bivy sacks collect less condensation than any other bivy bag sold in the U.S. All of the seams are factory seam taped. The floor is coated nylon taffeta, with a slightly tapered foot section for efficiency.
Both the foot and head ends of the bivy are boxed, so they won't cramp your toes or compress sleeping bag loft. The double storm flap and rain gutter have no sewn seams, so they can't leak. The dual slider zipper opens in the middle for adjustable ventilation and the opening is also covered by zippered no-see-um mosquito netting.
At 26 ounces, this durable, stormproof shelter is ideal insurance for that wall or alpine bivy. The Big Wall Bivy has a waterproof, welded, fabric-covered Spectra® runner sewn in the side for tie-ins. Comes with a stuff sack. Completely factory seam taped.
