Bests & Worsts Reviews from Amazon

I wore this on a bicycle ride under my jersey. It was 104 degrees. It was cool! I even tried one sleeve up to compare arms and the covered one was cooler because the radiant heat of the sun was hot! I sprinkled my sleeves with water and it was really cool for a while. I got it because my skin is starting to get age spots even with daily sunscreen so I have to cover up. I read reviews and got a large where I usually get medium. It was loose but not baggy. I would like it fairly tight to cycle in so next time I will get a medium.
