In all my years (15) and miles (approx. 200,000) of riding in an Aerostich suit, I have never had a wet crotch area. Might be because I have always, by reflex and without thinking about it, adjusted the suit every time I climb onto the bike so that there is nowhere for water to puddle in my lap area. I am sure that the zippers are a "weak spot" in any riding suit, but from personal experience they are not a problem for me. Guess I have been lucky.
