No cycling specific shorts for me yet. Winter I wear cargo shorts over base layer tights (no padding). Other seasons, I wear mesh athletic shorts, cargoes, or in the worst heat of summer, I often wear swim trunks. Sounds weird, I know, but the inner mesh lining holds the boys in place pretty well while allowing things to air out nicely as I ride. Also a plus is that I can easily wash the swim trunks with me in the shower and get a lot of days out of them before having to throw in the washing machine. Best of all, you can get em on sale for like $5 or $10.

I may get some chamoised lycra shorts/liners one of these days, but they'll either be the MTB variety or I'll be wearing them under some athletic shorts...
