evo.com | Leatt Bike Helmets > Young riders get the same 360deg Turbine Technology found in Leatt's adult helmets with the Leatt MTB AllMtn 1.0 Jr Bike Helmet - a lightweight trail helmet built to handle both low-speed and high-speed impacts, plus rotational forces through a genuine 3-in-1 safety system. In-molded impact foam handles the big hits while the turbine discs absorb lower-energy impacts associated with concussion. Fourteen vents with MaxiFlow air channels keep things comfortable on the climbs, and the adjustable fit system dials in a secure feel for small heads. 20 Vents Lightweight Polymer Compound Shell 360deg Turbine Technology The helmet is lined with turbines, which are 360 degmoving discs constructed from an energy-absorbing foam and material. This reduces rotational acceleration to the head and brain and absorbs energy upon impact at concussion level.
