Nammu Classic Solid Colors

The Nammu Classic Solid Colors is our best-selling swim hat — the one that started it all. Over a decade of swimmers, snorkelers, parents, and sun-sensitive customers have trusted it to stay on, protect, and hold up wash after wash.

Simple design, serious protection

Available in 12 colors — Black, Blue, Gray, Light Gray, Green, Orange, Pink, Pink n’ Bow, Purple, Red, White, and Yellow — the Classic Solid is a UPF 50+ hat built from 80% nylon and 20% spandex. It blocks 98% of UV rays, dries in minutes, and never stiffens or sags after repeated use in salt water or chlorine.

Stays on through anything

The signature Nammu adjustable tie-back is what sets this hat apart from every other swim hat on the market. Customers wear it for open-water swimming, snorkeling, kayaking, beach days, and water parks — and it stays put. Waves, dives, current, none of it moves this hat.

For everyone who needs it

The Classic Solid is one of the most popular choices among customers with alopecia, cochlear implants, and those going through chemotherapy. The soft, breathable fabric sits comfortably against the scalp, provides full coverage without heat buildup, and comes in enough colors that customers often buy two or three.

With over 100 five-star reviews and a 4.8-star rating, it’s the hat Nammu customers come back to — and the one they give as gifts.

Available in One Size (fits most adults and kids 2+) and XL (for heads over 21.5″ / 54.6 cm). Check the size guide or browse the full collection.
