Works great! He said when the wind blows, they are great at feeling cool. However, if he is indoors or there is no breeze, they are “hot as h-e-double hockey sticks” in his words.

I kept the small for myself for when I mow or do other yard work, and it fits fine. For reference on how it fit me for women looking at these for myself- I am 5’1″ and around 120ish, size c cup, and I typically wear medium in women’s shirts, small in men’s. Fits good, not too much compression in the forearm region on me, but this was made for men, and I like the fit.
