Another comfortable option is to try one of the inflatable "horse collars" They are used by professional fishermen and some deckhands... You can find them at Bass Pro Shop or other good sporting goods store. They inflate with the pull of a ripcord that activates a co2 cartrige. Another option is a Body Glove water ski vest, they are solid neoprene, cut large in the arm openings for freedom of movement,they fit snug so they don't ride up, very comfortable, and reasonably priced at Sam's Wholesale Club...
