CEP Arm Cooler Sleeves
Here's what other sites are saying:
Don't be fazed when your riding partner asks you why you're wearing arm warmers when it's 95-degrees outside, just tell them it's the CEP Arm Cooler Sleeve and watch them look at you in disbelief. The Arm Cooler Sleeve is designed to protect cyclists from the harmful effects of the sun during training. Featuring UPF 50+ sun protection, the Arm Cooler Sleeve won't leave your limbs red as a lobster. In addition to protecting your skin, the Arm Cooler Sleeve also features CEP Cool-Cell technology that reacts with sweat or water to reduce skin temperature by up to 6 degrees--and there is little better than staying cool on a scorching canyon climb.
