Alpina Rocket Youth - The ROCKET YOUTH is a pair of MTB glasses with a narrow frame and low height. Perfect for young mountain bikers. The individual look, modern mirroring and fashionable colors of the Rocket Youth set trends on the trails. And that's exactly what the MTB glasses are made for. The special design of the glasses ventilates the lens so that it doesn't fog up even on sweaty climbs. The adjustable nose pad ensures that the sports glasses fit well. Thanks to the low weight of just 29 grams, the Rocket Youth is particularly comfortable to wear.
