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.
