almost perfect
The XL mask fits my not unusually large male face very well. Finally, a mask that's big enough. The only (minor) problem is that the mask comes with an in-built pocket for inserting an additional filter (good idea!) but there's an opening on only one side, making it difficult to insert (that is, to push through) a flexible filter (like a coffee filter). To remedy this, I cut a slit on the other side so as to enable pulling the filter through. I also hemmed the cut edge, like the other one already was. It would be nice if the mask came with slits are both sides.
