Why invest in sun shirts?

According to the Skin Cancer Foundation, sun-safe clothing “remains one of the most effective forms of protection against sun damage and skin cancer. What’s more, sun-protective clothing is the simplest way to stay safe; unlike sunscreen, you never need to reapply”.

How do sun shirts work?

Sun shirts are rated with the UPF system, which stands for Ultraviolet Protection Factor. The material and weave are specially designed to protect your skin from both UVA and UVB rays that come from sunlight. This level of coverage protects your skin from premature aging, sun spots, and even skin cancer.

Lightweight vs. Medium Weight sun shirts

UPF is measured on a scale. A UPF rating from 20-49 is considered very good protection, while UPF 50 (which blocks 98% of the sun's harmful UV rays) is considered excellent protection. Our sun shirts begin at UPF 30 in the lightweight material then increase to UPF 50 in the medium weight material. This way, you can choose the level of protection and comfort in your sun-safe apparel to suit your personal needs.

Do I need sunscreen if I'm wearing a sun shirt?

As a brand who prioritizes safety and protection, we strongly endorse the use of additional sun-protective elements while wearing your Kastel shirts. Sunscreen, a wide-brim hat, and even gloves will further enhance your coverage from the damaging UV rays.
