Cooling Tech for Miles Under the Sun
The ActiveIce™ Spectrum Sun T-Shirt keeps you cool and protected through high-output days under the sun. Built for hiking, running, and active pursuits in warm conditions, it balances comfort and performance when the temperature climbs.
Powered by thermoregulating ActiveIce™ technology, it cools as your body heats up, maintaining a steady core temp through long efforts. The lightweight, breathable fabric wicks moisture, dries fast, and delivers UPF 50+ protection. Side slits free up movement, while chafe-free seams and dynamic reach patterning keep every stride and stretch smooth. Made with a recycled polyester blend and bluesign® approved materials for sustainable performance you can feel good about.
