Don't wipe out

....just kidding mate, I dunno. Only time I get a rash is my inside legs with long boardies. I stopped wearing long boardies Maybe the vest sux, maybe a springy would be better. Maybe you have the wrong size & its too loose or your allergic to the material used. Dunno I don't get a rash from my steamer, springy or long sleeve vest & clock up some hours in them.
