Sun Protection in the Water: Why Nammu Swim Hats Are a Must-Have

Did you know that water reflects up to 50% of UV radiation? This means when you are swimming, you are being hit by the sun from above and below. Sunscreen often washes off, clogs pores, or stings your eyes. Most regular hats are not designed for water; they fall off the moment you dive or the wind picks up.

To stay safe and enjoy your time in the water, you need a solution that is as active as you are.

The Nammu Standard: Comfort, Style, and Health

Nammu was created  to be the perfect balance of four essential elements for every swimmer:

Health (UPF 50+)

Our fabric blocks 98% of harmful UV rays. It is a permanent shield for your scalp that never washes away.

Stay-On Security

The tie-back design ensures the hat stays secure during surfing, diving, and vigorous swimming. It won’t float away.

Soft, stretchy swimsuit fabric that feels like a second skin. It is breathable and dries quickly, preventing overheating

Effortless Style

A bandana-style look that gives you the confidence to be seen. It looks like high-end swimwear, not a medical cap.

From the calm of a backyard pool to the waves of the ocean, Nammu is designed to stay in place. Whether you are snorkeling, kayaking, or just relaxing, you can stop worrying about your hat or your scalp health.

For those navigating hair loss or sensitive skin, Nammu offers an added layer of confidence and inclusion. You can participate in every activity without feeling exposed or restricted by your gear.

“I spent years trying to keep a baseball cap on while kayaking. It was a constant struggle. Nammu is the first hat that actually stays on in the wind and water. It is comfortable, keeps me safe from the sun, and looks great.”
