I've never had anything more than a bit of mild heat rash, even while riding 75-100 mi/day. It's entirely possible that clothing has nothing to do with it. Maybe it's your saddle. Maybe it's your bike fit. Maybe, and please don't take this as an attack, you just started adding on too many miles before some of your anatomy was quite ready for it.
