M Neck circumference 36-42 cm
How to determine the right size:
Measure the circumference of the neck or widest part, near the shoulders. A collar should be comfortable at all times. Therefore, when measuring the neck circumference, place 2 fingers between the neck and the measuring tape to ensure that the collar you purchase will not be too small.
These 2 fingers clearance is counted in the sizes we give above!
