How to Use Training Mask？
It's easy to wear a training mask.
First step: Put the mask right in front of your face, open the mask sleeve with your hands in the meantime.
Second: Combine the sleeve straps behind your head.
Third: Adjust the position of the ear area, until the mask fit into your face.
Fourth: Take a deep breath and check the sealing performance, if you feel the airflow comes out between your face and the mask, then adjust the position again, and tighten the sleeve strap, for better sealing and fitting.
