hi Davie
i have a Ping waterproof top and Dunlop waterproof bottoms. there are some really good waterproof clothing out there now, comfortable and light and warm too. i have played in some really bad weather and never had a problem with my waterproof. you have to watch as some are only shower proof and heavy rain does soak in, if its rainware it should not leak.
(shows you have good taste Davie, have you found it water tight.)
Gavin Green and Sunderland both look like good gear.

cheers
bill
