These are 75% cotton and 25% polyester and consequently are very poor at holding their shape. These will hang very loose and closely approximate traditional boxers. I originally bought the Hanes 95% cotton / 5% spandex Boxer Brief Underwear and ordered these by mistake. Beware, if you're looking for the more form fitting, shape holding pair, these are not them. If you like a lot of room to roam in your underwear, these are definitely for you.
