Familiarity: I've put it through the wringer
These arm skins work (mild to warm days), but on intense hot days.... my internal body temperature feels warmer. I was hoping that these skins would cool my arms on those hot days but that's not the case for me.
The fit is good, they are constructed well, and easy to wash.
