As cyclists, we spend a lot of time in the sun, so Pearl Izumi designed the Sun Sleeves to act as single-application sunscreen in order to draw a line between us and harmful UV radiation. The newest model of Sun Sleeves enjoys a higher UPF rating (50 instead of 40) and wider grip bands for a more secure fit.
Each color now also has different cooling technologies. The black option includes In-R-Cool material, which uses Coldblack technology to reflect the sun's warming rays. The white option uses Ice-fil, which involves adding a xylitol coating to the fabric's threads that reacts to moisture, getting cooler when it gets wet. Both options incorporate Pearl's Elite transfer fabric to wick moisture and keep you comfortable during the hot, sunny days when you'll really appreciate the Sun Sleeves' high UPF rating.
