Our garments are designed to block both UVA and UVB rays. These are the two primary types of ultraviolet radiation that reach the Earth and can cause skin aging, sunburns, and long-term skin damage. Learn more about UVA and UVB rays.

UPF stands for Ultraviolet Protection Factor. A rating of UPF 50+ means the fabric blocks at least 98% of UV rays, allowing less than 2% to pass through. It is the highest level of sun protection available for textiles. Explore the science behind UPF protection.

No, if you're wearing our UPF 50+ certified garments, you don’t need to apply sunscreen underneath them. However, for areas not covered by the fabric—such as your face, hands, or ankles—we do recommend applying broad-spectrum sunscreen. Find out how to fully protect your skin.

UPF refers to the protection provided by fabrics, while SPF measures the protection offered by sunscreens. SPF mainly indicates protection against UVB rays, whereas UPF protects against both UVA and UVB. Understand the difference in full detail.
