Outdoor Research Men's ActiveIce Spectrum Sun LS Tee

ActiveIce™: is a sun-protection technology that actively lowers skin temperature as you sweat. This groundbreaking technology works by using xylitol, which releases the same endothermic cooling reaction you get from chewing gum. That refreshing tingle you feel when you bite into a fresh piece of gum? That's the same effect your skin feels when Outdoor Research's ActiveIce products come into contact with water. The ActiveIce fabric collects moisture – or sweat – and actually uses that moisture to cool you down. Every ActiveIce™ product is infused with UPF 50+ sun protection so you can pass on the sunscreen where these cover you, and each is also breathable, lightweight, and quick drying. Choose ActiveIce™ whenever you plan to spend time in hot, exposed, sun-baked conditions.
