Can I help in your attempt to bring it back? I'd like to join.
I don't have anything just normal flexes. The olive one is drab. The black one is VERY old. I'd have to say 6-7 years. I wore it for years, I retired it 2-3 years ago. The foam is worn, the strap is so stretched it no longer fits.
I tried out different masks. The proto axis was nice, but not quite as light. The Sly profit I got later was a P.O.S. like wearing a bucket on your head and you can't hear ****. There was very little foam, it would dig into my forehead, so I had to get a headband in order to wear it comfortably. Also, considering it is a $90 mask with a dual pane lens(that was still in good shape), I was surprised when it began fogging during the late summer.
The proflex doesn't fog even with a single pane, it is light and breathes well, the solution to which mask I should buy was simple.
The new one is only a few months old and hasn't been out much. But I plan to put it to work as time goes on.
