How to adjust Ozone Sport mask size?
There are three sizes of masks S / M, L, XL. Thanks to their universal size, everyone should find the right one for themselves.
S/M – for older children and very slim women weighing up to 50 kg
L- for women and very slim men
XL- for men over 65 kg
Velcro allows you to adjust the fastener up to 4 cm in the head circumference, which allows everyone to adjust the mask to the face.
