Exhale Emergency Bivy Breathable Sleeping Bag


128 In stock

The Mountain Lab Exhale Emergency Bivy Breathable Sleeping Bag is waterproof, windproof and—unlike most other emergency blankets and bivvies—is also breathable. This is a huge benefit for anyone who needs to hunker down and stay warm in cold conditions outdoors.

The Mountain Lab Breathable Bivy is constructed of a four-ply material developed by NASA to breathe effectively yet still reflect 70-90% of a person’s body heat. The advanced material is much stronger than a typical lightweight emergency bivy or blanket.

The Breathable Bivy features waterproof seams, a 1/4 side zip for easy entry and a drawstring hood closure to help seal in the heat.
