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.
