i can not decide if these are really short shorts or panties...the material is awesome, for a guy its incredible, these are like the improved version of boxer briefs. The material is like a nylon spandex kind of deal, lots of support for the horse. They don't ride up (though i don't mind if panties do, its no different than a thong to me) i ordered 12 different panties and these are in the top 3...they were the last ones i opened too and are possibly my favorite now. will absolutely buy more from this brand in the future
