I use the helmet for sparring in Jeet Kune Do. For limited sparring exercises he is super. Light fist and elbow strikes and head butts he dampens well off, the field of view is slightly limited when wearing a face shield, but ok. The only drawback is the internal padding, which is in fact made of fabric. It is therefore to be expected that the helmet absorbs the sweat and begin to smell musty after a while. On the whole, but I can not complain. Those who want even let a little crash in training, makes nothing wrong with the part.
