Sun Protection That Actually Swims.
Created by a mom, designed for active lives, and loved by everyone
It started with a simple problem: Sun hats don’t swim. As a mother of three active kids, I struggled to find sun protection that worked in the water. Baseball caps got soggy, wide-brim hats flopped over eyes, and everything else floated away the moment my kids dove in. I needed a solution that was UPF 50+ safe, comfortable enough to wear all day, and secure enough to stay on during a cannonball. When I couldn’t find it, I made it. Since 2008, Nammu has been the go-to swim hat for families, athletes, and outdoor lovers worldwide.
