The Sweet Protection Durden is a brand-new MTB goggle with minimum frame and maximum field of vision. This goggle features a new way of mounting the goggle strap, where the strap is on out outside of the frame, making sure you get the best possible fit to both our Fullface- and Trail/Enduro specific helmets. There is no vent foam for maximum ventilation when pedaling hard. Its a fairly large goggle with a 1.3 mm thick injected single lens with oleophobic- and hydrophobic coating treatment as well as anti-fog treatment on the inside. There is a hook interface on the bottom part of the lens which makes it easier to fit into the frame, and easier to change. 1.3 mm thick injected sylindrical lens Super hydrophobic and oleophobic Anti-fog
