i dont hink those have a removeable lining so itl probly rot im not 100% sure tho...i was gona get 1 a while back
i just bought a FLY helmet from ski md and it's mint! has a removable liner too. fits nice and snug and stays in place when your head hits the water hard!
If money allows try and go for carbon fibre to keep the weight down...Full size motocross helmets get to heavy when waterlogged!...Most of us down this way use mountin bike helmets....Look on trademe for a good deal.
