Men's Sun Long Sleeve Tee

Thermoregulating Technology with Certified Materials for Sunny Days

The Sun Long Sleeve Tee is built with thermoregulating cooling technology and certified eco-friendly materials, perfect for keeping body temperature in check while hiking, backpacking, climbing, or setting up camp.

This tee is built with an ultra-comfortable, breathable, and quick-drying polyester blend treated with proprietary cooling technology that reacts to your body's rising temperature by cooling down your core, keeping you in the sweet spot longer while pushing the tempo or working hard. The chafe-free design, built-in stretch, and UPF 50+ are welcome essentials for long days spent under the sun, delivering comfort and maximum range of motion on reachy boulder problems or tight slot canyon squeezes.

Purpose-built for staying cool while spending long days in the mountains under the sun, this Sun Long Sleeve Tee is a warm-weather staple for every outdoor enthusiast.
