These multilayered facemasks quickly became our family favorite when the pandemic hit. I can't even count how many we have now (likely 20+), and they are the first that everybody in our family reaches for. I wear mine 8+ hours per day as I teach face-to-face and they are some of the only masks I can tolerate to wear for that length of time. We've submitted a few special requests, and they've been met quickly and professionally. We highly recommend Perimeter Face Masks!-Ashley H.
