So what is the difference between "unisex" and "women's" arm warmers?
Both styles of PI ones are stretchy and fit me fine. My DeSoto arm coolers, OTOH, which are not stretchy, will NOT stay up - the gripper opening is larger than the bicep, which I find just bizarre. If I were a man with enormous delts would that help? (It doesn't really seem like it. Most of the belly of the delt is above the armpit joint which is the highest the grippers can ride.)
And, has anyone tried the Zoot arm coolers? Those are looking tempting to me.
