Bibler
Hooped Bivy Sack
Mountaineering Bivy
A super light, Hooped Bivy that is designed for climbers, bicyclists and other light weight fanatics. 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
