: we guarantee proven safety.

SOFTVISION: The rounded surface of the lens is created by at least one cylindrical surface that affects the light rays in a perpendicular plane to the glasses, making image processing much easier. In order to avoid distortion of the transmitted image, SOFTVISION lenses are equipped with an optical correction that sharpens vision and increases the perception of surrounding objects.

DURAMAX: Reliably safe: The material used in the manufacture of the visors is made of impact-resistant polycarbonate developed specifically for protection against rough damage. It is up to 20% lighter than conventional plastic visors and extremely safe. Safety is guaranteed by testing in an accredited laboratory.

POLAR FOAM: Very soft and gentle. The multi-core construction of POLAR foam is characterized by its high stability. By combining a unique composition and different densities of each layer, a high impact resistance of the foam is achieved. The outer layer made up of microfleece is skin friendly, absorbs and wicks moisture away from the face and provides a high level of comfort of use.

ANTIFOG: Technology in which an invisible layer of nanoparticles is applied to the inner visor, effectively preventing water vapour condensation on the surface and thus eliminating fogging .The use of this technology maximizes the life of the glasses while maintaining high clarity of the lens.

ICE VISION: Optically Clear. In collaboration with Italian manufacturers, the highest quality lenses are produced in a laboratory environment, eliminating image distortion and transmitting the highest possible image quality. The integrated heat shield balances the temperature differences between the external and internal environment of the goggles, thus significantly reducing the formation of frost on the lens and contributing to the high comfort of using the goggles.

FLEX FIT: Extremely lightweight. The unique Flex Fit frame technology significantly reduces weight, and the highly elastic FLEX CORE construction material ensures maximum frame flexibility. Thanks to its low weight and high grip, the goggles achieve greater protection as the frame forms a compact unit with the face, which better absorbs and distributes the impact of impact.

ANTISLIP: Anti-slip silicone printing on the inside of the goggle strap prevents sliding on the helmet and keeps the goggles firmly in place exactly as you put them on.

DESIGNED IN CZ: All products are developed and designed in the Czech Republic
