The minimalist, four-season Black Diamond Twilight Bivy is built from water-resistant and breathable NanoShield fabric that keeps weight to an absolute minimum and packs down incredibly small, making it ideal for an emergency shelter or as a sleeping bag cover. Built with a zippered entry across the shoulders, it’s easy to get into and use while sitting up.
Superlight Series bivys are constructed with NanoShield—Black Diamond’s proprietary breathable single-layer fabric. NanoShield is extremely water-resistant boasting the highest water column rating of any breathable, single-layer fabric. This is thanks to our exclusive Silicone Nanocell coating, which allows the fabric to remain light, soft and packable.
