Klim Radius Pro Tinted (Threat Yellow) GEMIN-EYE ANTI-FOG: Anti-fog treatments were first developed by NASA during project Gemini to provide their spacesuit with a lens that would fight condensation in space. Likewise, the best snowmobile goggle should perform for every rider and withstand extreme conditions. After sourcing the best materials and methods around the globe, KLIM is the first to offer GeminEYE anti-fog. Rather than a simple hand application on one side of the lens, we dip the entire inner lens in the GeminEYE formula as a dual shield against fog up to 3X longer than our previous best lens. AIRCHAMBER VOLUME BOOSTING DIMENSIONS: The KLIM Radius Goggle is designed with more volume between your eyes and the interior surface of the lenses. This higher volume of air created by KLIMs AIRCHAMBER is affected less drastically by changing temperatures and humidity levels, keeping condensation saturation to a minimum. The KLIM Radius Goggles AIRCHAMBER maximizes the volume of the face-to-lens airspace so the chance of fogging and having your vision compromised is diminished. AIR FORCE INDCUTION and FRESHAIR Ventilation PREMIUM CASE & CLEANING CLOTH: Included with all Radius models is a two-chamber/dual-fabric cleaning cloth which doubles as a goggle/extra lens storage bag. Radius Pro models will include a premium hard case to protect your goggle. QUAD TESTED POLYCARB PREMIUM UV400 LENS: KLIM developed the PolyCarb Premium dual-pane lens with an extremely advanced Polycarbonate (PC) outer lens for a more durable and scratch resistant experience. In order to deliver the highest quality, the Radius Goggle goes beyond the industry standard by undergoing 4 unique durability tests and impregnated UV400 protection. The combined technologies with the PolyCarb Premium Lens make the Radius Goggle inherently more durable, scratch resistant and vivid than the competition. RADVENT FRAME VENT FOAM: KLIM, in conjunction with GORE Labs, documented breathability and air-permeability performances of numerous frame vent foam structures. Through this research, KLIM found the perfect lens ventilation foam. Our RADVENT foam provides snow and debris-blocking properties with air permeability and breathability performance equal-to much less dense foams. This allows maximum air and water vapor to escape without allowing snow or other debris to penetrate into the AIRCHAMBER.
