Material Feel & Function: Lightweight & breathable – The fabric appears thin but durable, allowing airflow while still giving full coverage. Moisture-wicking – Performance polyester pulls sweat off the skin and dries fast, keeping you cool when the temps climb. 4-way stretch – The way it lays smooth across the body suggests stretch built in, so it moves with you instead of restricting. Soft, smooth hand feel – Not stiff like traditional camo cotton. More athletic, almost slick but comfortable against the skin. UPF protection – Sun shirts like this are typically engineered to block UV rays, ideal for long exposure days. Quick-dry performance – Whether sweat, rain, or water exposure, it won’t stay heavy or soaked. The hood is made from the same performance fabric, giving neck and ear coverage without adding bulk. Overall, this material is designed for heat, sweat, and mobility something you can wear all day without feeling weighed down. NOTE: For a looser fit upsize
