The Bivy Booty is the ultimate waterproof overshoe for basecamp. It can be ideally combined with the EXPED Camp Booties, Down Socks or Camp Slippers. The 1 cm thick, non-slip, raised sole made of recycled material and the heel guard protect and insulate. The insole is removable and can be replaced if necessary. The elastic drawstrings allow a snug fit of the Bivy Booty to the foot. These can be operated with gloves or one-handed. The seam-taped, PFC-free outer material is vapor-permeable and protects against moisture and humidity with a water column of 10,000 mm.
