The particular suit was under development for three years until 88Motorsport and Ursuit got it perfectly made for pwc users. If you use it for practicing then you don't have to wear anything under it. We have been using it winter time even here in Finland (+1 air, +2 water). Pajalin, owner of 88Motorsport, mentioned in his comments. His team rider Mikko used extensively on a stand up and he was very satisfied. This pictured Drysuit is available from 88Motorsport (88Motorsport.fi and 88Motorsport.se) at 799euro and the price is final including VAT.
