Sun shirts provide lightweight upper-body coverage for hiking, travel and long days outdoors. They are designed to make sustained coverage comfortable, which can be more practical than repeatedly applying sunscreen beneath clothing.

Compare verified UPF rating, sleeve and neck coverage, fabric weight, breathability, drying speed and ventilation. For humid conditions, airflow and moisture management are especially important.

UPF measures ultraviolet protection from fabric; SPF relates to sunscreen. A UPF 50 fabric allows roughly one-fiftieth of ultraviolet radiation through under test conditions. Continue protecting exposed skin and use shade and timing where possible.
