ActiveIce Spectrum Sun T-Shirt – Men's

When the miles stretch long and the sun is punishing, the ActiveIce Spectrum is our go-to sun shirt for trail runners and hikers who won't back down in Southern heat. ActiveIce fabric uses evaporative cooling to actively pull skin temperature down as you sweat, while UPF 50+ blocks harmful rays on exposed ridges and open trails. A relaxed athletic fit handles everything from long trail runs to backcountry hunts.
