Our goal is to make the most comfortable mask to help you breathe cleaner air. That's why we created three sizes so you can pick the perfect one. To get the best fit you will need two measurements.

The good news is that Nanoknit will stretch to the contours of your face to create a comfortable seal. We've also included adjustable elastic earloops so you can tighten your fit depending on your preference or activities. That's just part of what makes our mask unique.
