A demonstration of the durability and strength you can expect from the Top Ten Protective Mask. As you can see, it is strong enough to support an average person. But, when greater force from jumping is used, the mask flexes and returns to shape without shattering. This mask is specifically designed to be used as a unit with Top Ten Head Guards and should not be attached to head guards of other brands. Although, the Protective Mask is extremely safe, it should not be used for full-contact training or against heavy striking.
