This is the BANK spherical lens model, featuring DICE's "A-BLOW SYSTEM" ventilation function. Includes an extension belt for helmets. The lens is PHOTOCHROMIC/LIGHT GRAY/MIT BLUE MIRROR. This lens combines the "no mirror peeling, no scratches" features of MIT lenses with photochromic technology (light adjustment) that changes color with UV light. It automatically adjusts brightness, allowing use in a wide range of environments. There are some minor scuff marks. They are difficult to see in the photos, but please check the photos for details. The "breathing goggles BANK" are enthusiastically supported as the most innovative gear in the modern snowboarding scene. The "A-BLOW SYSTEM" internal ventilation system exhausts warm air from inside the goggles and draws in fresh air from the outside, preventing lens fogging. Belt extension parts: Attach to the space between the DICE goggle belt buckles and attach to the snow helmet strap. Supports the length of the goggle belt and fits many helmets. *Can be used if the belt buckle does not fit into the snow helmet stopper, or if the helmet is large and the goggle belt is not long enough. #DICE #DICE #SWANS #Swans #Bank #RIDGELINE #BANK #LightAdjustment #Ventilation #Mirror #MIT #belt #clip #BeltClip #ExtensionBelt #ExtensionParts #Helmet
