Description
The Nammu Classic Reversible gives you two hats in one — flip it inside out for a completely different look without packing an extra hat.
Two looks, one hat
Available in B/W Pattern and B&W Abstract, each reversible hat has a solid side and a patterned side. One day you’re wearing sleek black, the next you flip it to a bold geometric print. It’s the ideal travel hat: one item in your bag, two options when you get there.
Same trusted Nammu protection
Beneath the dual-look design is the same UPF 50+ nylon-spandex fabric that makes every Nammu hat a reliable sun shield. It blocks 98% of UV rays, dries in minutes, and uses the signature tie-back design that keeps it snug through dives, waves, and active water play. One reviewer wore it snorkeling in the Red Sea. Another used it on a scuba diving trip. It holds.
Perfect for trips and travel
Customers love this hat for vacations specifically — cruises, beach holidays, snorkeling tours. You get the variety of multiple hats without the luggage space. As one reviewer put it: “Great option for bringing one cap on vacation and getting two looks.”
Note: This style fits a little snugger than the standard Classic — if you’re on the edge of sizes, consider sizing up. Check the size guide or browse the full collection.

Great option for bringing on cap on vacation and getting two looks! I love the reversible option! Wear it with a classic black swimsuit, or any kind of pattern. It’s as wonderful as the Nammu classic, with a double feature!
excellent fit and quality…look forward to using them on our Red Sea Adventure
Très beau produit de qualité. Peut-être un peu serré.
disappointed as too tight to wear. should have asked for replacement prev. but overlooked due to seasonal madness, what can u do?
Idéal pour la plongée sous-marine, tiens très bien en place. Je recommande : )
