Technical innovation and independent third-party testing ensures the fabrics are UPF 50+. The fabrics use a combination of weave (tighter is better), color, weight and additions of the best active ingredients found in sunscreens, millions of the sun-bouncing minerals, titanium dioxide and zinc oxide infused at the fiber or fabric level. Even with multiple washings and exposure to sweat, chlorine and salt – the sun protection never washes out.
All Coolibar fabrics have been approved as an effective UV protectant for covered areas. Coolibar is the first clothing company to receive The SCF's Seal of Recommendation. *Source: CDC: Skin Cancer Rates by State
