Bolle NORTHSTAR - Ski Goggles - blue hawaii matte/sunrise

TECHNOLOGY:

Flow-Tech® Ventilation: Designed to optimise ventilation on the inside of the lenses, Flow-Tech® ventilation helps prevent snow build-up and to reduce fogging for exceptional visibility.

Equalizer® Ventilation: Equalizer® technology provides high performance anti-fogging through an insert placed between the lenses. It uses a ventilation system to regulate the atmospheric pressure between the lenses, eliminating moisture and condensation.

P80 + Anti-Fog Coating: The P80+ coating on the inner layer spreads water molecules that may form on the surface of the lens to reduce fogging, which could affect your vision.

Carbo Glass: The outer layer of the goggles is covered with a specific treatment that protects the lens from scratches.

LENS CONSTRUCTION:

Spherical: Spherical lenses are built on a base curve in both the X (horizontal) and Y (vertical) axes. This makes the spherical lens more rounded to follow the shape of the retina. They provide a wider field of vision, which is helpful in busy environments with lots of trees, trunks or rocks. Spherical lenses help you perceive relief and also help improve your performance when skiing downhill.

CATEGORY:

Category 2 solar lenses will filter out 58% to 82% of ambient sunlight. This protection is effective in medium sunlight conditions. Category 2 lenses can be worn in periods of variable sunlight and between seasons, for example at the beginning of spring and the end of autumn.
