Outdoor Research ActiveIce Sun Sleeves

Picture yourself halfway up an exposed ridgeline with the sun hammering down and no shade in sight. That's exactly when these Sun Sleeves earn their keep. Outdoor Research built them with an upgraded ActiveIce thermo-regulating treatment that reacts to your body heat and dials up the cooling sensation right when you're working hardest, so your arms stay comfortable instead of cooking under direct sun. The lightweight, breathable fabric wicks sweat and dries fast, so you're not stuck with clammy sleeves on a long summer hike. A snug bicep grip keeps everything in place through scrambles and pole swings, while UPF 50+ protection blocks harmful rays without needing to reapply sunscreen every hour. Pull them on for a dawn patrol hike, a day on open water, or any outing where the sun doesn't let up, and let your sleeves handle the heat so you can focus on the trail ahead.
