Best-selling ActiveIce technology works more efficiently and effectively than ever before. Now featuring the same thermo-regulating formula as our proprietary ActiveTemp, this new version of ActiveIce dynamically adjusts to your body's temperature to cool you faster when you need it most. 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. The ActiveIce Chroma Full Sun Gloves provide superb back-of-hand sun protection, and have a perforated synthetic suede palm that releases heat without compromising on protection.
