There are sun shirts, and then there's 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. Experience more than just (UPF 50+) sun protection. Why settle?
