These are a one off creation and have been hand crafted from Copper, Brass and Leather.

The leather has been hand stitched and copper hand beaten. Joints have been welded using Silver Solder and are verry strong.

All of the brass rivets were individually hand made as were the fixings such as the straps adjusters and side swivels.

Inner lense is tinted yellow and outter lense is a dark welding lense.

These goggles were worn by the brewer of Epic Breweries whiles brewing their new Portamarillo beer and were on the 3rd episode of the Brewmasters TV Series.
