Now I religiously put on Bullfrog SS every morning since I am of scottish descend and usually before I headout. I need a sunscreen that stands up to sweat my usual is lacking. I pulled my boy in a bike trailer for 15-20 miles why we were running errands around Hilo, Hi and I got a little more sun than I would like. I know re-apply, re-apply, but its a pain in the tuchus while you are riding or running. I do re-apply after surfing. I think the added humidity here is killing me as this wasnt a problem for me in SoCal or AZ. So does anyone have a suggestion for sunscreen that is sweat proof?
