Technologies

FogStop

It is an anti-fog coating used on the inside of the lenses of Alpina brand glasses and goggles. It guarantees clear vision, even in high humidity.

Airframe Venting System

An intelligent ventilation system used in Alpina ski goggles. Thanks to the ventilation holes with foam covers on the sides and bottom of the goggles, constant air movement is possible inside the goggle body, which disperses moisture and prevents the lens from evaporating.

Mirror

Mirror technology, as used in Alpina helmets, involves coating the lens with multiple reflective layers. This provides effective protection against intense glare and infrared radiation.

OTG (Over The Glasses)

The OTG (Over The Glasses) system has been designed for people who wear prescription glasses. Thanks to the specially widened frame design and contoured interior, it allows for comfortable wearing of goggles without pressure on the lenses or frames. It ensures full visibility, comfort and a stable fit even during prolonged use.
