Black Diamond Winter Bivy Sack

Black Diamond Winter Bivy Sack description

The Black Diamond Winter Bivy was designed both as a minimalist bivy sack and a winter sleeping bag cover. Great for keeping down sleeping bags dry in wet coastal climates. Extremely lightweight, this innovative bivy sack is made of a breathable silicone encapsulated polyester ripstop fabric. This fabric allows the Winter Bivy to pack down so small that it can be carried in the pocket of your jacket. Ideal for protection in all conditions, the Winter Bivy can also be carried as an emergency shelter for climbers, hikers, and bikers out on day trips. During the summer months, you can use the Winter Bivy as a lightweight alternative to a sleeping bag. Zippered entry across the shoulders is conveniently positioned for easy access and sitting up.

Bottom Line: Small, lightweight, and totally functional - the Black Diamond Winter Bivy is a must have on any wilderness adventure.

I got this sack for a trip to Red Rocks thinking it might come in handy if I went in to the backcountry. Little did I know I would be using it the first night because we were short one tent. It kept me dry and extra toasty even though the outer shell was wet with dew. It also packs insanely small. Darn good sack at an awesome price!

I'm sure this is a great bivy for minimalists, although there are a couple of items you may want to consider before ordering. All seams are untaped and there are perpendicular seems running across the top of the toe box area (top & bottom) as well as down the sides. The shoulder zipper is not nearly as convenient as a full length side zipper. At 55% humidity @ 55 degrees, it seemed to collect condensation as redily as a Mountain Hardware SL conduit bivy.
