How to wear good and replace the filter

Faster shipping then expected, and shipped with in the US. The product was legit not a knock off
The fit is fine the Velcro is good quality. I wear a cotton mask under it to protect my fellow humans during exhalation since there is no filtering through the ports on the mask.
Perfect and air tight and never cones loose if you pull the straps in an 'x' like the second example in their video. Amazing mssk built using gas mask like mouth-cup filter.
This Mask is amazing. I've bought a number of buffs, home make face masks and surgical masks but have been waiting for Base Camp to come back. Very comfortable!
