I agree with the previous review, I am currently on my 4 th fabric harness. Inside the fabric is a strip of plastic, however it is not one continious piece. In the front where the mask mounts the plastic ends coming in from the sides to the circle. That is where I have had failure each and every time. The fabric stretches there because the end of the plastic strip is not connected to anything. At a certain point the fabric begins to tear ane the end of the plastic strip becomes exposed. At this point the mask has lost it's ability to maintain a constant hold on the mask. At this point the torn fabric is the only thing holding the mask together and it's only a matter of time before it completely tears apart.
In my opinion this mask is a very good idea, but with a poor design.
If the plastic internal frame were all one piece this problem would never occur. And instead of purchasing my 4th one I would still be using my original one.
Oh, I believe I see the problem !
That would be four times less sales for the manufacturer and the distributor.
I guess that's what they call, "Planned Obsolescence"
