What is the purpose of the stop-valve?
We are aware that in this period of health crisis the air exhaled through the valve of our mask can be restrictive if the barrier gestures are not respected.
Created in 2015 for bikers and then for cyclists, we have received many requests from people wishing to equip themselves with the mask to protect themselves from Covid-19.
Our team of experts in filtration has then developed a solution that comes to close our valve and thus protect your loved ones from the virus: The stop-valve.
This solution is clipped inside the valve.
The valve stop does not alter the breathability of your mask.
