The Bivybag Duo UL is an ultra-light, small packable and robust emergency bivy bag. It is the ideal companion on any trek and protects in an emergency from wind and weather. With a shoulder width of 55 in (140 cm), it also offers space for a second person.

The taped seams provide protection against rain and moisture. In addition, three floor openings reduce the formation of condensation. The bright color makes you visible in emergency situations.

This practical bivy sack can also be used as a protective cover when resting or as a poncho for one person.
