The only drawback is that the sides and nose can allow air to enter/exit and if you have glasses it requires a lot of adjustment to prevent fogging. I think if you have a fuller face then that's less of a problem (air getting out around sides and top), but my face is rather thin. Overall it is very comfortable.

Love these masks and made in USA Love these masks. Sturdy and stylish, easy to wear and avoid glasses fogging. Fast shipping, and LOVE they are made in USA. Pricey but worth it. Have ordered several times to share with family and friends. Prefer the classic Nano in black with subtle logo over the new brand, so hopefully they remain available.
