The Mountain Equipment Ultralite Double bivi bag is a very lightweight, small, wind- and waterproof emergency bivy bag for two people.

The Ultralite Double Bivi is the big brother of the Ultralite Bivi and offers space for people in the case of an emergency. It offers protection from wind and weather and delays the cooling process whenever you'll have to stop for a storm, can't avoid an unplanned night outdoors, or wait for help to arrive.
