An appetite for performance.

The Marmot Men's Interval Shirt devours laps for breakfast, works the weights for lunch, and cycles the streets for dinner. This polyester shirt dries quickly, wicks moisture, and provides a UPF of 30 while the stretchy mesh panels bring the breathability, airflow, and stretchy mobility. An athletic fit includes raglan sleeves for uninhibited movement and a drop-tail hem for extra coverage. Flatlock seams help reduce chafing on long runs, and reflective details ensure visibility in low light scenarios.
