The Black Diamond Twilight bivy is a minimalist bag style bivy that’ll provide shelter for the fast and light traveler or stow it in your pack for an emergency.
The Black Diamond Twilight bivy is a four season bivy sack that features frameless construction to keep weight and pack size to an absolute minimum. It’s built from water-resistant and breathable NanoShield fabric – Black Diamond’s proprietary breathable single-layer fabric. NanoShield is extremely water-resistant thanks to the exclusive Silicone Nanocell coating, which allows the fabric to remain light, soft and packable.
The Twilight bivy features a mesh panel at the zipper entry for bug-proof ventilation and the zippered entry across the shoulders makes it easy to get into and use whilst sitting up. It’s ideal for weather protection during fast-and-light pursuits and makes a good emergency shelter too.
