SIZING CHART


Reference this head-form diagram and sizing chart to determine the correct size Airgami mask to get.
Sizes overlap, so your best fit will be the smaller mask that's in the sweet-spot for both cheek-to-cheek and nose-bridge-to-just-under-the-chin measurements.
Make sure you measure approximately straight-line distances, not curves.
Look straight into a mirror while holding a ruler against your face and horizontally aligned with your lips when measuring the side-to-side distance. Measure from almost 3/4" left of the left corner of your mouth to almost 3/4" to the right of the right corner of your mouth.
Place the ruler against your face beside your nose and measure from the bridge of your nose just beneath your eyes to the base of your chin.
Use both measurements to find the smaller size where both ranges, side-to-side and nose-to-chin, will fit your facial measurements.
If your face is short and wide then choose the smaller size whose maximum distance from right-side to left-side fits you.
If your face is tall and thin then choose the smallest size whose maximum distance from nose-bridge to slightly below-the-chin fits you.

Sizing Micro-adjustment

The Airgami mask has a patented micro-adjustment mechanism that lets you customize your fit within one of the above size ranges.

The harness elastic controls tension on the folded bellows. The greater the tension, the smaller will be the perimeter of the mask that comes in contact with your face and vice-versa.

The same harness elastic controls tension on the ear loops. The greater the tension, the tighter the mask will press into your face, creating a tighter seal and vice-versa.

INCREASE HARNESS TENSION around the ears and mask pressure against the face by pulling down on the harness knots located at the outer harness holes on the chin side.

DECREASE HARNESS TENSION around the ears and mask pressure against the face by pulling up on the harness ear loops at the outer harness holes on the nose side of the mask.

TIGHTEN TO FIT a smaller face by pulling down on the ear loops where they enter the middle harness holes on the chin side. This gathers the side bellows.

LOOSEN TO FIT a larger face by pulling up on the elastic stitches where they enter the middle harness holes on the nose side (use an opened paperclip or toothpick to pull up on the stitches). After loosening, fan the side bellows to even-out their spacing.
