What UPF certifications do your hats have? How do you test them?

The majority of our line is rated UPF 50+, the highest possible rating, blocking over 98% of UVA and UVB rays. All of our materials are tested at independent labs in accordance with AATCC 183-2014, the international testing standard for UPF ratings in textiles. We conduct UPF testing on our products to ensure they meet our standards. Please check individual products for the specific UPF rating.
