This mask is meant to be attached to the FAST-helmet. It is nice and easy to operate. The primary hook-up point is the NVG-mount on the front of the helmet and to secure it in place, there are two fast attachement points that are to be locked into your FAST-helmets side rails.
The frame of the mask is made out of hard composite plastic and the breathing holes are coverred with steel mesh which makes the fogging problem of your glasses and goggles history!
This mask attachment is light, weighing about 190 grams. The mesh part is made out of strong steel mesh and makes it very well air conditioned even in the hottest weather of the summer.
