Men's Eclipser Short SleeveThere are sun shirts, and then theres the ECLIPSER. While many shirts offer effective protection, most are hot, sticky, and uncomfortable during physical activity. Ultra lightweight and silky soft, the ECLIPSER features skin cooling yarns for active comfort under the sun. An innovative, seamless design transforms our engineered, odor resistant fabric into a breathable, underarm mesh for superior airflow, ventilation, and quick dry performance.
