I'll probobly get hammered for this but Patagonia makes the best boardshorts I've ever had. I've literally never had a rash (in that area) since I started wearing them and I've never had any trouble from the seams, zippers, buttons or key loops. Every other pair of boardies I've ever had one or more of those problems. It also seems boardshorts have become so expensive (some costing $100!) that Patagonia isn't any more at about $50 I think and they have a lifetitme guarantee. They make multiple lengths-pick up a couple with the 23 inch outseam (23's I think they call them) and you won't get burned on the top of your knees in the tropics or get rash from the side of your board.
