An incredibly water-, wind-, and bug-resistant bivy sack that’s designed for climbers who sleep on exposed rock ledges, the Black Diamond Big Wall Hooped Bivy weighs about as much as a lightweight tent, yet is one of the most stormproof sacks on the market. In addition to a sewn-in flexible wire, a dual-sided zipper that opens in the middle, and a mesh-covered opening for adjustable breathing space, this bivy also has an integrated, waterproof tie-in point for secure anchoring.
Sewn-In Wire – A flexible wire creates airspace overhead while keeping the weight of the bivy relatively low at 30 ounces.
Dual-Sided Zipper and Mesh-Covered Opening – A mosquito and no-see-um net at the entrance keeps bugs out while the dual-sided zipper opens in the middle for easy in and out.
Secure Anchoring – An RF-welded tie-in point is waterproof and ensures the bivy stays put.
ToddTex Single-Wall Fabric – This bivy is constructed of waterproof, windproof, and breathable ToddTex with a polyurethane-laminated floor.
Taped Seams – The seamless construction of the double storm flap and rain gutter ensure bad weather stays out, while the rest of the seams are factory taped.
