improved version top notch
Now that they have redesigned the mask with the adjustable ear stops, its a five star product. I previously ordered one before they put the upgrade on it, and it was still a quality mask...but it was stiff on the ears at first. Couldn't imagine it that it would be a "one size fits all", so i gave it a break in period.  With the adjustment straps, you can easily find the sweet spot with the fit. No more sore ears. The construction materials other wise, are good quality. Worth the price, especially considering the masks you can buy in stores that cost more. The extra filter layers just make the value even better.
