How to choose your size

  • Size XS typically fits a young child from 4 years old
  • Size S typically fits a teenager or petite adult
  • Size M typically fits older teens and average adults

  • Size L typically fits taller and broader adults

    We recommend using these measurements as a guideline. Take the measurement from the tip of your nose to center of your ear and refer to the chart below to find corresponding size.

    The XS and S sized masks are listed under Copperline KIDS and the M and L are listed under the regular Copperline mask.

    PLEASE NOTE: The mask fabric stretches. If you think you may be between sizes, we recommend sizing down.
