From the black diamond website:
Compact, ultralight, stormproof bivy sacks, Hooped Bivys use a sewn-in flexible wire, a dual-slider zipper that opens in the middle and a no-see-um mesh covered opening gives you some adjustable breathing space. It’s built from waterproof, windproof and breathable ToddTex with a polyurethane-laminated floor. For security, the double storm flap and rain gutter use a seamless construction, and all other seams are factory taped. I‘ve had the bivy a few years, but its only been used a small number of times, and is in perfect condition.
I‘m asking $100. Will ship to the US only.
