I purchased this headgear for my Krav Maga training. Part of our training is to take part in boxing and kickboxing classes. I've never been formally trained in boxing so my instructor "strongly recommeded" I get a good set of headgear. I wasn't happy with the basic headgear being sold at our school because it lacked an adjustable chinstrap so started looking at the Revgear line. I've only been using this headgear for a couple of weeks now but am very happy with it. It comes true to size (using the chart on this website), it's comfortable, and it protects my poor head from the enthusiastic blows from my fellow students. I even got a "nice headgear" from the instructor.
