Good Mask EXCEPT the Straps Keep Breaking
The straps on these masks kept breaking, sometimes before you even got to use the mask one time. We found ourselves having to carry 2-3 at a time as a backup since the straps would break frequently.  Would only buy if you are going to take the time to use super glue or something similar to reinforce the straps before use, otherwise it's a waste since you'll go through them so quickly and risk being caught without a functioning mask when they break at the wrong time. Bummer, because otherwise these masks seemed good .
