Simms Solar Sombrero is composed of 100% lightweight nylon with HT Teflon® treatment. Featuring a wide brim, the Solar Sombrero protects from the sun's damaging rays.
Through a combination of fabric construction, design and finish, Simms offers a wide range of clothing that features a minimum of 30 UPF (very good) up to 50 UPF (excellent). UPF is the Ultraviolet Protection Factor indicating the quantity of the sun's UV radiation absorbed. A rating of 50 allows only 1/50th of the sun's UV rays to pass through the fabric, thereby reducing your skin's UV radiation exposure significantly. All of Simms' UPF finishes last the life of the garment, an industry standard of 30 washings.
