Review on 💨 BDL Sport Mask: Carbon Reusable with Exhalation Valves, Adjustable & Protective for Men and Women - Includes 4 Filters by Nathan Vaughn

This mask does not work as it should. It does not protect the surrounding area as it exhales the wearer's unfiltered breath, which is the exact opposite of the purpose of camouflage. The saying "I will protect you (with my mask) and you will protect me (with your mask)" does not apply to open vents, which allow breath to escape without being filtered, thereby removing breath that can transmit infection. They are good for gardening or painting, but not for viruses.
