Our size charts are provided for your convenience and reference only. Everyone is shaped and created uniquely therefore we can not guarantee the fit of any gear. Fit is also subjective to the martial artist. I for example can not even stand to wear a head guard. When I was required to in a certain organization I wore an XL in Macho even though I measured for a large, I hate a tight chin strap.
Since all manufactures have different sizes and specifications we have provided the charts most used for Century Martial Arts, Macho Martial Arts, Proforce, Kwon and others we will add as we see fit.
If you need any help choosing please ask us first or consult with your instructor.
