This is a very comfortable mask. Full coverage of the ears and face. The lenses come with an anti-fog coating which actually works really well and the vent holes help with airflow to keep me fairly cool while wearing this mask. This mask has not fogged up at all on me during use. My glasses are another matter, unfortunately. This mask is glasses friendly for those, like myself who wear prescription glasses. The wrap around lense style allows for unimpeded peripheral vision. Disassembly of the mask to remove the lenses for cleaning is very simple but is not detailed in the manual, at least not that I could find. Only took about 2-3 minutes of fiddling with the mask to figure it out though. The mask also comes with a visor that can be easily installed using the included tool and requires removal of the forehead protection plate shown.
One downside is that, while the mask does breathe quite well, my prescription glasses have fogged up pretty quickly in hot weather while wearing this mask. Not sure if this can be fixed by installing a fan or not. The second downside is that while the mask is low profile it is still a bit difficult to use my iron sights. The mask does flex a little (it is made of plastic so it doesn't flex very much) and I can use my sights fairly well but it is not quite as simple/easy/comfortable as I was expecting. For the price, I can easily overlook a little discomfort with using the sights.
Definitely money well spent, but I still need to either figure out how to stop my glasses from fogging up or get contacts to use this during the summer months.
Simple and easy disassemble for cleaning/maintenance
Reliable anti-fog coating on the lense
Iron sight use is better than some masks but not quite as good as I had hoped for.
Anti-fog coating on prescription glasses, for those that wear them, will still be necessary in hot weather.
