The Crysallis with zippered no-see-um netting under the zippered eVENT cover.


Integral Designs expands their line of eVENT fabric bivy sacks. Their Crysallis Bivy is now available in eVENT, joining the ultralight Overbag and Micro Bivy, the technical South Col and Bugaboo, and the palatial (by bivy standards anyway) Unishelter.

The Crysallis is Integral Designs' foul weather bivy. Featuring a rear facing tunnel vent and an absence of skyward facing zippers, the Crysallis can be fully zipped up and provide a totally waterproof and well ventilated shelter. Situated between the sparse sub-20 ounce Overbag/Micro Bivy and the 31 ounce Unishelter, the eVENT Crysallis rounds out Integral Designs line of eVENT bivy shelters - the most extensive in the industry.

With its wire-stiffened dome, the Crysallis creates almost as much space inside as the larger and heavier Unishelter with its curved aluminum pole. Also, unlike the Unishelter, it can be deployed without any stakes.

In storm mode, side-oriented waterproof zippers seal out precipitation, while the tunnel vent and breathable eVENT fabric reduce condensation.
