Abus MountZ Youth Cycling HelmetBe it a weekend mountain bike adventure or the daily ride to school, the Abus MountZ Youth Cycling Helmet provides young cyclists with stylish and protective performance whenever and wherever they pedal.At the heart of the high-quality MountZ Youth Cycling Helmet is Abus' protective In-Mould design technology. This construction technique has allowed Abus to keep the weight low but protection levels high. An EPS foam core provides vital shock-absorbing protection from impacts to the head during a crash.Bonded to the inner is a structurally strong and durable polycarbonate outer shell. This fends off those inevitable knocks and bumps you get from low overhanging branches and trailside overgrowth. It also adds durability from the every day (ab)use it will see from keen young cyclists.Cool ComfortAs young riders build speed and confidence, they'll quickly be pushing their ride limits and working up a good sweat. But with 5 inlet vents and 8 exhaust vents, they can look forward to cool airflow as the pace hots up. There's also a built-in bug mesh, keeping out those buzzing nasties while zooming along the trails. Zoom Ace Urban adjustment systemA good fitting helmet is essential for both safety and comfort.
