Helium UL Vestibule

The Helium UL Vestibule from Outdoor Research is a clever extension for the Helium UL bivy sack that offers you additional space and weather protection. The waterproof construction creates a protected area for your equipment while significantly increasing the comfort of your bivy.

The construction uses a single trekking pole as a support and can be set up in minutes with two aluminum pegs and two guy loops. Reflective elements improve visibility in the dark and make it easier to find your bivouac.

The Helium UL Vestibule offers maximum functionality with minimum weight gain, making it the ideal addition for minimalists who don't want to compromise on comfort.
