1. PU Material: The head guard is made of PU leather and the material properties make it difficult for dirt to penetrate. When it is covered with dust or sweat during outdoor training, simply wipe it with a damp cloth after training and it is ready for the next use. 2. Easy adjustment of the buckle: The headgear is equipped with an adjustable buckle design to adapt to different head sizes. Regardless of the size of your head, the buckle can be flexibly adjusted to achieve comfortable and secure wearing comfort. 3. Lining puts an end to odors: The lining of the headgear has been processed to reduce odor formation. After several days of consecutive training, there are no unpleasant odors inside the headgear. When you wear it again, it always feels fresh. 4. Hearing protection design: The hearing protection part features a transparent design, protecting the ears while allowing sound to pass through normally. In loud training and competition environments, users can still capture all kinds of sound information.
