The sun is both a strong ally and a superior foe, meaning that we need it to survive, yet it's hell-bent on harming us should we choose to worship it with our bare skin. For this reason, we created our Deflect UV Arm Covers. Don't let the full-arm coverage fool you, as they aren't necessarily for keeping you warmlthough 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 either comfort or temperature management. This is furthered with a next-to-skin NILIT Breeze yarns that reduces body temperature, much like the feeling of cool, minty breath after chewing certain gums. 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.
