Chafed legs from pantyhose

I also remember my mom dealing with this and some things she did to prevent it. To prevent chafing, you first have to prevent moisture sweating. Those who know this all too familiar feeling, will know the outcome. It has an in-built evaporative cooling system that draws moisture away from the skin, reducing sweating and leaving the wearer feeling cool, dry and comfortable. Chafing shorts are stretchy and luxurious to touch and fit on the body snugly without restriction. You may also feel less muscle strain in the thigh. On top of that, they keep your thighs happy and rub-free.

It then quickly dries that moisture, leaving the area cool and dry, which is why they give relief from chafing as you need moisture to chafe. Your thighs are touching, you start getting hotter, your thighs start to get sweaty, sticky and your skin starts to irritate. You need moisture and movement in order to chafe.
