Children’s ski goggles: Bolle NEVADA JR have double cylindrical glasses that create a thermal barrier with better sealing and optical quality. Special OTG treatment allows you to wear them with prescription glasses. The lenses have a metal layer for better contrast and reduced glare. The special patented P80™PLUS/CARBO GLAS technology decreases the risk of the lens getting scratched or foggy. Bollé downhill ski goggles are designed to be compatible with most helmets on the market. The patented air vents regulate air circulation inside the goggles to prevent the lens from fogging.
