The ALPINA DOUBLE JACK with spherical lens are modern ski and snowboard goggles in classic style. The mirrored and contrast-enhancing Quattroflex Lite lens ensures sharp vision on the slopes. The large spherical lens of the ALPINA DOUBLE JACK Q LITE provides unrestricted all-round vision. The Quattroflex Lite technology clearly emphasises contours in the snow and makes it easier to recognise ice sheets. Additionally, the mirrored lens provides 100% protection against UV-A, UV-B and UV-C rays. An air cushion between the individual goggle lenses creates a thermal block that prevents the lenses from fogging up. The goggles are also constructed so that prescription spectacles can be worn underneath them. The comfortable frame adapts perfectly to your face and is pleasant to wear thanks to the soft foam padding. The adjustable hinge strap holds the goggles securely on your helmet.Features:- Strong contrast enhancement- The surface reflects infrared rays- Non-slip fit on the ski helmet- Good ventilation of the interior- 100% UV-A, B and C protectionSpecifications:- Weight: 130 GramTechnologies:100% UV-A, -B, -C protection:- All Alpina lenses provide 100% UV-A-, -B-, -C-protection and thus guarantee excellent eye protection.Airframe Venting System:- Airframe venting is an intelligent ventilation system for ski goggles. Air vents at the sides and bottom with special foam covers allow a continuous movement of air within the body of the goggles. This circulation of air disperses moisture preventing the lens from misting up.Comfort Frame:- The Comfort Frame is designed in such a way that it adapts perfectly to the shape of the face thanks to the flexible plastic webbing in the forehead and cheek area. The result: an ergonomic fit that ensures the best possible comfort and prevents pressure marks. At the same time, the ski goggles are perfectly finished.Double Lens Thermoblock:- With Doublelens Thermoblock, an air chamber is created between the two lenses to prevent a cold bridge. As a result, the view is fog-free and always optimal.Fogstop:- All Alpina ski goggles have a Fogstop coating. This is not smooth but rough - on a microscopic level. This prevents moisture from forming a closed layer. So the lens doesn’t fog up and the view remains clear. Hicon:- Hicon is the name for a certain orange tint of the lens. This colouring has the property of significantly increasing contrasts. This makes the view clearer and better, which increases safety on the way down. The effect is particularly helpful in diffuse lighting conditions such as fog or snowfall.Mirror:- Mirror is a lens on which multiple reflective layers are applied. They provide protection from harsh glares and infrared light. Mirror is not only the feature of a highly functional lens, it’s an element of style.over the glasses (OTG):- Over the Glasses are designated as the glasses you can wear over normal vision aids. They are designed to allow enough room inside and space on the sides for a glasses frame.Skid Grip:- Skid Grip is a special rubber coating on the inside of the eyewear strap. They prevent the ski goggles from slipping on the mostly smooth surface of the ski helmet.spherical Lens:- The Spherical Lens is spherically domed, providing much better panoramic vision. The enlarged volume inside also optimises climate management inside the goggles. Thermoblock and Fogstop effectively prevent the ski goggles from fogging up.
