Sierra-Men-Tee

$95

Made with Coolcore Tyndall recycled fabric, this Tee offers lightweight breathability, advanced moisture-wicking, and thermoregulating comfort for everyday training. UPF 50+ sun protection keeps you covered under harsh conditions, while four-way stretch allows for freedom of movement.

Reflective details enhance low-light visibility, and the relaxed fit allows for unrestricted movement and airflow. Finished in a clean chalk tone, it’s technical where it matters and effortless everywhere else.
