Review on Jyipsonm Cooling Arm Sleeves for Men and Women - 10 Pairs of UV Protective UPF 50 Sports Cooling Sleeves for Outdoor Activities: Driving, Golfing, Fishing, Running, Cycling, Hiking - Includes 5 Black and 5 White Sleeves by Jim Bijelic

A four-hour midday bike ride exposes a cyclist to approximately 20 times more UV radiation than it takes to burn. That's why you see so many cyclists with long sleeves, even in summer. Sunscreen only works until you need to reapply it, which is difficult without walking away with slippery hands or smearing sunscreen on your eyes. Nice set, 10 pairs, 5 black and white. Lightweight and stretchy, with a UPF 50 meaning they are comfortable and suitable for most skin types. Spending a lot of time in the sun can be a lifesaver (literally).
