Womens sweatpants

The other day while shopping, yes shopping, with my roommates at the college store we can across some black sweatpants, they said Cortland on them and were soft, we all thought it would be neat if we got the same kind. The lady at the counter looked at us kinda strange when we were checking our sweatpants, well we get back to the room and first notice something strange that there is a string for the waist, something we haven't seen before in sweatpants, and trying them on was odd and very uncomfortable. Well we look at the receipt and it turned out they were for females, needless to say we were baffled. My thing is the other pair of sweat pants that we were looking at which turns out were guys were not as soft as the girls, why? Why cant guys have sweat pants with a nice soft fabric, i just don't understand, could someone please enlighten me on this topic cause i seem to be at a lost
