The ActiveIce™ Sun Sleeves utilize ActiveIce™ technology and UPF 50 to keep arms, wrists, and hands cool and protected from the sun while hiking, trail running, cycling, or paddling. Our ever-popular Sun Sleeve provides the highest sun protective coverage by combining a glove and a sleeve and featuring a bicep grip to hold itself in place. Now featuring the same thermo-regulating formula as our proprietary ActiveTemp™, this new version of ActiveIce™ dynamically adjusts your body's temperature to cool you faster when needed. Still wicking and complete with a UPF 50+ sun protection rating, ActiveIce™ is the perfect companion for anyone who spends serious time in hot, sweaty, sun-baked conditions. Best-selling ActiveIce™ technology works more efficiently and effectively than ever before to keep hands cool and protected during long days in the mountains or in the bike saddle.
