I'm at risk(more risk than most) of skin cancer and managed to find full length boardies called kite pants from a U.S. brand Ultra Nectar - bought from x-shore kiting in qld 2 yrs ago, these are good - now wear s2 (same as radiator) pants most and long boardies sometimes. Not sure if they make these boardies any more but give xshore a try. Forget it if you're trying to look cool but sure beats melanomas
