While some say, "no life till leather," we never associated it with developing leathery arms from playing roulette with the sun. We know that our message of protection against ultraviolet rays isn't alone in the universe, which is why we created our Deflect™ Arm Covers. Don't let the full-arm coverage fool you, as they aren't necessarily for keeping you warm—although they could hit the sweet spot on a very moderate day. Instead, they were developed to keep your skin protected from the sun's harmful ultraviolet rays, all without sacrificing anything to comfort or temperature management. To do so, we constructed them from a material that's about as fine as silk, our VaporRize™ fabric, that features a microdenier construction, meaning that you'll find it to be supportive and accommodating in all the right places. This has been coupled with a right- & left-specific design that prevents any unwanted pinching or chafing, all while serving up a UV 50 level of protection.
