We will deliver it in a completely sealed ZIP lock case.
By using CORDURA for the outer fabric, it is highly abrasion-resistant and durable, allowing for repeated long-term use through washing.
The lining is made of smoothly knit fabric, keeping you cool and dry when it’s hot, and warm when it’s cold, making it very comfortable to wear. By attaching the included adjuster parts, it prevents ear chafing from the rubber string and prevents pain.
*Hand wash in lukewarm water is recommended.
Due to hygiene reasons, returns and exchanges are not possible except for initial defects.
