My husband's favorite. He tossed out all his old underwear when I order these the first time!
He has long legs and a short torso and they never ride or bunch. They don't show the crack either!
We've reordered them a few times now and they're great. His old cotton ones were always disintegrating, these have held up great and still look brand new. They are really sturdy and he says they're the most comfortable underwear he has ever had! He has me order more regularly, because god forbid, they ever not be available and he not be ablate get them! (From a wife's perspective, they're very attractive on too.)
