Biker anti-pollution masks

The Biker anti-pollution mask is an excellent price alternative with its removable KN95 filter and two exhalation valves, for those who are reassured by fogging or exhaled CO2. The Biker respiratory mask is available in one size, be careful it is rather large but as it is very flexible and stretchy, it is suitable for all adults. This is a very good cycling mask. It is also perfect for bikers. Biker masks are not Frogmask masks.
