As of 2020, nearly all airlines and travel authorities require face masks during travel, some have now specified that passengers should only wear valve-less masks during transit. We want to be able to help people living or traveling through areas with specific regulations. 

Our PRO mask is designed with a valve to ensure maximum breathability and reduce Co2 buildup, especially during high-intensity activity. Our PRO mask is ideal for those suffering from respiratory illnesses, against smoke inhalation from wildfires, and for DIY against dust particles.
