your peace of mind start on your head with nammu sun blocking swim caps

Swim Hats Built for Every Water Sport

Kayaking, paddleboarding, snorkeling, surfing — if you’re on the water, the sun doesn’t stop. Nammu Sport Swim Caps are built to keep up, staying put through paddle strokes, waves, and hours outside.

Stays On, No Matter the Sport

Regular hats blow off, slide off, or need constant readjusting. Nammu’s secure fit is designed for movement — snorkeling face-down, paddling hard, or catching a wave — so you can focus on the activity, not your headwear.

UPF 50+ Protection, No Reapplying

Sunscreen wears off. A Nammu hat doesn’t. Every cap blocks 98% of UV rays for your scalp, ears, and hairline — protection that lasts the whole session, not just the first hour.

Built for Every Age and Every Adventure

From first-time paddlers to seasoned divers, Nammu hats come in sizes for kids and adults alike. Whether it’s a weekend kayak trip or a daily ocean swim, there’s a fit for the whole family.
