Description
Cocoon is a place to find shelter in extreeme [sic] conditions and environments. Hang it off a tree or a cliff face or anywhere you else you need to. Inside, the user is comforted by a warming colours and materials that will ensure they stay warm no matter what the conditions are like outside.
Co-Designed with Billy Harney
(It's like a life jacket you can use to knock down trees and coax unwilling girlfriends)
I nominate John and Bill for the useless gear contest.
