The F100 Arena mask uses a stainless steel shell coated with a durable layer of ultra-thin anti-bacterial Nylon. It has a 350 Newton bib for protection and is padded for comfort. The lining is durable and water resistant to keep the bib fresh.
The mask is fitted with the old traditional spring case making it slightly heavier than the Arena mask and not as adjustable. As traditional masks go this is the best available on the market.
European World Combat Champion Richard Kruse "The Contour-Fit back is the ultimate in mask comfort. Once you have tried it you will never go back."
