Then, pull the end of your Snugz with the black line so that it extends about half an inch (1.25 cm) past the rubber cushion.

  1. Give your Snugz a few stretches before applying if you feel it is too tight on your mask.
  2. Make sure that the black seam is pushed inside of the mask enough so that it ends up behind the inner edge of the mask cushion.
  3. Note that the breathability of Snugz will leave you with a different sensation on your skin—your skin will feel cooler and dry. For some patients, this can take some getting used to, but it will help keep your skin irritation-free.
