Kask Optics creates new glasses with unique rotating arms

Made-in-Italy shades are easy to adjust and swap out lenses

Kask Optics, the offshoot of Kask helmets, has finally debuted its new range of glasses and like Kask’s helmets the glasses are 100 percent Italian made. The new glasses brand is called KOO, and its first range of products is called Open.

The frames have a unique flip-in arm design, which sees the arm rotate at the hinge point and turn in on itself for storage. The rotation is stepped so that you can adjust the angle of the lens whilst wearing to help clear fogging. The glasses were also designed to fit snugly on to Kask's Protone helmet, and the arms clear the helmet shape too. The nose bridge is adjustable too, and included in the set is a second, smaller sized nose bridge.

Kask seems to have sweated the details, with lens changes made remarkably easy. Simply flip the retaining tabs on the frames and pop the lens out — with little stress-inducing bending or forcing, like we’ve had from other switchable systems.

The lenses are made by Zeiss, and included in the package is a multi-layer dark and a clear lens.

Kask is aiming the glasses squarely at the top-end with a price tag of €199 / £169.99 / $239 for the twin lens set, or you can add a third photocromatic lens for an extra €50. The glasses are available in 12 colourways, all inspired or matched to Kask’s helmet colourways — most notably the Protone.

Kask has also added a wider range of sizes to the Protone and Mojito, with the Protone now available in a small alongside its existing medium and large. The Mojito is now available in small, medium, large and XL.
