Excellent sun protection hat.

The hat is excellent covering head, face and neck from UV. I where it whenever we have sunny days. I have chosen a bigger size, than I would normally choose for a hat, but that really works for me, otherwise I would find it very hot. I would really recommend this product

Dear Sir,

Thank you so much for your kind words!

We're delighted to hear that the Arcachon sun protection hat is meeting your expectations and providing effective UV coverage for your head, face, and neck. Choosing a slightly larger size to stay cool is a smart idea—comfort is just as important as protection. We're thrilled you’d recommend the product and truly appreciate your feedback.

Best regards from the Ker Sun team!
