Sun Hats by RoniGirl launched in April 2015. It is a line of Sun Hats that are both fashionable and protective. Not all sun hats are created equal. Sun Hats by Ronigirl are Unique! Why are they different? These hats are UPF 50+ lined with outdoor furniture/umbrella fabric, receiving a UVA rating of 99.90% and a UVB rating of 99.90%. Many hats claim to be UPF 50 + but they are not. These hats were sent to a lab recommended by The Skin Cancer Foundation for testing in order to receive this high rating. The hats are adjustable, foldable, washable reversible and they come in a small pouch. It is easy to throw into your pocketbook, car side pocket, fanny pack, bicycle basket, golf cart, or any other small space so that it is accessible and you will always be protected. For every hat sold we donate to The Skin Cancer Foundation for research, awareness, and a cure.
