SIZE GUIDE
To find the correct size, we recommend you to combine the Eye-Chin Distance Measurement and the Weight Measurement below.
Eye-Chin Measurement
To get the right size, measure the distance between the lower end of your eye and the lower end of your chin and follow this size guide:
Recommended size Eye-to-Chin (cm) Eye-to-Chin (inches)
XS Less than 8.5 cm Less than 3.3 inches
S 8.6 cm - 10.5 cm 3.4 inches - 4.1 inches
M 10.6 cm - 11.7 cm 4.2 inches - 4.6 inches
L Over 11.8 cm Over 4.67inches
Weight Measurement
Use a weight scale to find your weight and compare it to the table below to find your size:
Recommended size Weight (kg) Weight (lb)
XS 12-30 kg 26-65 lb
S 30-50 kg 65-110 lb
M 50-75 kg 110-165 lb
L Over 75 kg Over 165 lb
If you get different recommendations from the two methods, follow the one from the Eye-Chin Distance measurement.
If your weight or eye-chin distance is on the borderline, pick the bigger one to ensure a better fit.
