Black Diamond Hooped Bivy Sack

The Bibler Hooped Bivy Sack is a superlight, bivouac sack designed for climbers, bicyclists and other light weight fanatics. The hoop has 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, the hooped bivy sack collects 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 Bibler Hooped Bivy are boxed, so they wont cramp your toes or compress sleeping bag loft. The double storm flap and rain gutter have no sewn seams, so they cant leak. The dual slider zipper in the Bibler Hooped Bivy opens in the middle for adjustable ventilation and the opening is also covered by zippered no-see-um mosquito netting. At 22 ounces, this durable, stormproof shelter is ideal insurance for that unplanned bivy. Measures 90 x 35 (long version is 99 x 35) and comes with a stuff sack. Completely factory seam taped.
