1. PU Material: The box head protection is made of PU leather and the material properties make it difficult for dirt to penetrate. If it gets covered with dust or sweat during outdoor training, simply wipe it off 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. The buckle can be flexibly adjusted to achieve a comfortable and secure fit. 3. Lining puts an end to odors: The lining of the headgear has been processed to alleviate odors. After several days of consecutive training, there are no unpleasant odors inside the headgear. When you wear it again, it always feels fresh. 4. Ear protection design: The ear protection part features a transparent design that protects the ears while allowing sound to pass through normally. In loud training and competition environments, users can still capture all types of sound information.
