I wash them every time I wear them.. Which I realize isn't great for athletic material, so depending on the ride i'm going on, I might just wear regular athletic shorts (like knit material). I don't put my cycling shorts in the dryer.

They do still provide a cushion, but not as much of one,. They're supposed to be quick drying for after the swim. I find them more comfortable. But I don't go on super long bike rides either.
