The best protection will come from N95 and KN95 masks, but they can be tricky to wear comfortably while exercising. There are currently two sports masks that are ideal for Covid Protection.
Fits GREAT, feels very comfortable looks nice. I have no problems breathing through it and its filtering superbly, im sure! I could wear this mask all day with no problems! Not only will I give this mask 5-Stars, it gets 3-THUMBS UP, good job in innovation!!!!!!!!!!!!!👍👍👍
