Black Diamond Winter Bivy

A cold-weather Superlight bivy sack, the versatile Winter Bivy by Black Diamond is built from water-resistant Epic by Nextec fabric that keeps weight at an absolute minimum and packs down incredibly small, so you can tuck it away for an emergency shelter or add it to your gear as a sleeping bag cover. Built with a zippered entry across the shoulders, it�s easy to get into and use while sitting up.
