This is the mask as described in this Avon Brochure PDF
Essentially, it is a modern ambidextrous mask with built in drinking capability and the option to add powered mic/spkr system, etc. It takes standard 40mm NATO cans and has a flexible one piece lense system that will flex enough to actually use your low mounted ironsights or ACOG, etc. Note that this is not the newer system (as I understand it) sold to LEO's that cannot withstand regular use with CBRN agents. You can also get prescription lenses to insert. It has a six point mounting system with mesh panel to keep cool. The Blackhawk pouch has a multitude of options for mounting, but is just the pouch included.

Blackhawk pouch in black (awesome by the way)
Used filter because no one throws it away evidently. :-)
Asking $175 shipped CONUS. PP OK with fee percent added.
I am selling because the pesky Kifaru addiction came knocking again.
