Free of fuss, the Ex Officio Exo Dri Tee is a performance shirt that will take you from 10K to after party feeling dry and comfortable. The Exo Dri Tee is made of a lightweight jersey fabric that wicks moisture and dries 4x faster than cotton---which is saying a lot. The fabric is also treated to resist odors and protect you from the sun. Flat-locked shoulder seams prevent chafing and offer a comfortable fit. The bottom line on the Exo Dri? It's all about you.
