While any plastic bag can be used to haul your wetsuit there are better ways of transporting it post dive. The American made Baggu Wetsuit Bag is designed to carry the soggy gear and keep it apart from things you’d rather stay dry.
Originally designed for surfers it is made from water resistant 18 ounce vinyl and offers an exterior pocket for plenty of extra storage. Unlike canvas or other bags this one can be hosed down and hung out to dry.
