Hate having to smear sunscreen all over your skin prior to a ride? The only thing worse than dealing with messy sunscreen that is supposedly sweatproof but still ends up greasy is forgetting to put any on your skin, only to wake up the day after a ride looking like a cherry tomato. Since sunscreen is a hassle but protecting your skin from the sun's harmful rays is a necessity, what you need is a pair of sun blockers. Also known as sun sleeves, slipping on these blockers is much easier than dealing with sunscreen. And while they fully cover your arms, you don't have to worry about them creating extra heat during your ride. Instead, they're actually designed to help you stay cool and minimize sweat.
