And I'd recommend the armless long johns with seperate jacket/vest style suit.Works for both winter and summer then.
As for talc... forget it!They ain't called wetsuits for nothing.
Aaaaand, not really intending to open any doors here, Vaseline would provide better relief from chafing your bits, with some fishers wearing bikeshorts or boyleg jocks over the Vaseline under their wetsuit.
One good addition I can make to Bruce's tips... when trying to get back into a wet or somewhat damp suit...slipping a plastic bag over your hand or foot first will let you put it on real easy!
As soon as you get cold in a wet suit take it off, dry yourself and warm up again first before getting back in.... and don't be hopping into a wet/damp wetsuit when you're already cold either! Your body is telling you something you'd better NOT ignore.Could be fatal.
