Our guarantee

At Nammu, we stand behind every product we sell. If you’re not completely satisfied with your swim hat or swim shirt, we’ll make it right.

Return & Exchange Policy 

We want you to love your Nammu hat. If it’s not right, we’re happy to help with a return or exchange within 30 days of delivery.

How it works
Returns and exchanges are processed only after we’ve received the item back at our facility — we’re not able to issue a refund or exchange while a return is in transit. Once received, we’ll inspect it and process your refund or exchange within 3–5 business days.

Shipping time
We can’t control how long a package takes once it leaves our store, or once your return leaves your hands — carrier delays are outside our control on both legs. Tracking is provided so you can follow your shipment’s progress.

Condition
Hats must be unused and in their original condition to qualify for a return or exchange.

Return shipping cost
Customers are responsible for return shipping costs. If there was a mistake on our end, contact us and we’ll take care of it.

Refunds
Approved refunds go back to your original payment method.

Nammu reserves the right to refuse a return or exchange if the item shows signs of use, damage, or alteration inconsistent with normal handling.
