so you had all these great BD wiregate biners and you said "there's no way BD can improve on these babies." fortunately a BD engineer was in the room with you and accepted your challenge. sometime later...voila! the Hoodwire was born! this is one of those things that you really only notice when you switch back to using a different biner. then you notice how much more functional these ones actually are. just buy one a couple and try them out, you'll notice an improvement.
