Although inexpensive, these AeroTech shorts feel flimsy and insubstantial. The fabric is thin and lightweight. They don't compress the leg muscles as well as more expensive shorts.My major complaint, though, is that within two weeks of purchase, the material at the crotch wore through from friction with the saddle. None of my other shorts, more expensive and made of more substantive lycra, have done that. These shorts can now only be used for liners, not the purpose for which I bought them or for which they were advertised.They rate one star only because the chamois is reasonably comfortable and delivery was prompt.
