We've added a new colour into the Cmax Frank collection with a dark grey option. All of the unique Bunker Styling and performance. Long placket with fabric button down collar finished with Bunker Silicon Shield on the chest. CMAX is a high performance polyester fabric that wicks sweat away from the body to the garments surface where it can then evaporate, keeping you more comfortable and cool during your round of golf. Our CMAX performance product is now combined with our new Polygiene technology, keeping odour free during the most testing on conditions.
