If you have a mask that you want to have a robust, durable and light-weight mount fitting to, we can do it. Just send us your mask and we will fit the bullet camera mount. Just let us know whether you want it for our Actioncamera 420 and 480 range (19mm diameter) or for our 520 range (21mm diameter). Send the mask to our usual address. The mount swivels 360 degrees for the ultimate shots.
