The ActiveIce Spectrum Sun Long Sleeve Hoodie is built for long days in the sun when body temperature regulation and sun protection are a priority. ActiveIce™ technology actively cools during active use, keeping core temperature in check as the body works hard. UPF 50 sun protection keeps skin protected from the beating sun, and the quick-drying, breathable fabric is lightweight and features a movement-mirroring stretch for ultimate comfort. The chafe-free design with dynamic stretch is supremely comfortable when worn with a pack. Designed for comfort and performance in warm, sunny conditions, the ActiveIce Spectrum Sun Long Sleeve Hoodie is an essential piece for staying protected while working hard in the alpine and beyond.
