Review on Ultimate Comfort: Washable & Reusable Translucent Internal for Unmatched Experience by Sean Flint

ADVANTAGES: They are light. They keep the mask off your face, which is why I took it. They even fit snugly around the edges of the mask, reducing air leakage. CONS: If the mask is not made with tabs there is no way to attach the mask to the barrier, the double sided tape will not adhere to the barrier making it necessary to hold the barrier to the face whilst wearing the mask over it becomes. every time. It is more difficult to breathe as air leakage is reduced. By holding the mask away from your face, the ear straps will tighten and start hurting sooner if you can even put the strap on your ear. For all that being said the mask touching my face was driving me nuts, the pros outweigh the cons. I will continue to use them.
