The Alpacka Caribou with cargo fly is an ultralight, full-size bikeraft or ultralight hunting raft that rolls up small for stashing in a pack or on your handlebar roll. The Caribou is unlike anything else on the market; it combines the stability and load carrying ability of a rockerless hull with the whitewater and wave performance of a rockered hull, helping you stay upright and get over the top of the waves.
