I've seen talk in a thread from a couple of weeks ago about the advantage of wearing a wetsuit and how some people like to put people down because they wear one. It was mentioned that their can be a great advantage by someone that wears a wetsuit.
Given all factors kept equal, in OW, on something like a one mile course what could you expect to gain by wearing a wetsuit versus wearing something like cutoff jeans. Also, what could you expect to gain by wearing a swim cap versus not wearing a swim cap.
Inquiring minds want to know.
