Karnik UV Protection Cooler Arm Sleeves 1pair for Bike/Hiking/Golf

After having surgery for melanoma, I was advised to protect myself from the sun. Since I run marathons, this was the answer to my problem. They are very comfortable, and actually feel cool, even in direct sun.

They worked ok at first even though they were a bit tight, then after I used them a few times, the fabric got very thin in places so I would not buy them again.

Not very durable.
