I tried it but only one of my son's friends liked it. For myself, I don't like the nosepieces because they make my glasses sit wrong. I ended up altering a pattern to put a fold at the top, so that I can slip it underneath my glasses a bit. Much more comfortable and no problems with fogging. It has 3 pleats on the sides plus bottom pleats and has a lining and filter pocket. I've only made one so far and it's hard to talk with it on so I'm going to add about 1/2" to the folded edge and see if that works better.
