The smalls are a touch smaller than Calvien Klein or Alfani's small.
The fabric feels just little rougher than spandex.  kinda like pantyhose.
They don't conform well to my backside. I have a pair of champion running shorts, and its the same thing. Kinda like to two identical halves sewn together, rather than two separately cut and tailored halves.

bottom line; i might get again, if i were on a very tight budget.
