An MMA headgear needs to stay in place and you should be able to roll on the mats with it without any problem (changing the position etc.). This is why you need the best MMA headgear and not a boxing headgear.
I have sparred with a good MMA headgear and bad ones as well. So I know how much difference this can make for your safety and training performance.
I have a lot of experiences with MMA equipment, researched a myriad of MMA forums and also verified purchase reviews as well. According to these, I gathered the most quality products on the market. Below you can find the thorough reviews of these amazing headgears, my experiences, sizing information, brand overviews and at the end of the writing, there is a guide for choosing the right MMA headgear as well.
