HOW TO GET THE SIZE OF YOUR FENCING MASK
You should get the maximum possible circumference of the head, so using a tape measure, start from the tip of your chin and go through the ears to the top of the head, then come back to the starting point.
Always buy a mask of a size right for your head or a bigger size.
The size would be the following:
XS: 62 – 64 cm
S: 64 – 66 cm
M: 66 – 68 cm
ML: 67 – 69 cm
L: 68 – 70 cm
XL: more then 70 cm
XXL: more then 72 cm
