All masks come with elastic straps that can been hooked around the ear. Straps come with a toggle to tighten the straps to the measurement you find the most comfortable. For extra comfort, try sliding the straps so that the knot sits under the fabric of the mask.
IMPORTANT: Make sure the straps are tight enough that the mask is tight to your face. A loose fitting mask will compromise the efficiency of the mask. We recommend wearing it for 5 minutes to test it before putting it to use in public.
