KEEP YOUR ITEMS SECURED: Giant Loop Rubber Boa Straps take their name from a docile, worm-like snake, native to Oregon's high desert where Giant Loop is located. Rubber Boas are the most northerly of boa species, and they kill prey by constriction. Our straps apply dynamic tension with stretch elastic shock cord and a simple locking slot, creating a dead-solid connection between plastic fenders and relatively small and lightweight gear, even in demanding off-road terrain.
