Protect yourself from the sun and heat, with De Soto Arm Coolers. Yes, Arm Coolers...contrary to what you wear in the winter to keep your arms warm, this set of sleeves keep you cooler in hot weather. The special moisture-radiating material actually offers a cooling effect. They are guaranteed to keep your arms cooler in training and in racing than not having anything on. These sleeves do not have an SPF rating yet, but worn with sunscreen underneath they will offer even more protection than sunscreen alone. Sizes: XS, M, L. Made in the USA.
