LS2 Stream II Lux Helmet The LS2 Stream II Helmet stands out with its aerodynamic, sporty design crafted using Kinetic Polymer Alloy (Kpa), which incorporates nanotechnology to blend aramid fibers and a high-end polymer. This combination allows the helmet to manage energy efficiently with flexibility, reducing the impact of energy without the rebound effect found in lesser materials. It meets the ECE 22.06 specifications with its Advanced Rotational Energy Management Technology (Arem), ensuring superior protection. The design includes a rear spoiler for improved ventilation, alongside 3D laser-cut foam cheek pads and a removable, washable liner for exceptional comfort and easy maintenance. With three shell sizes and five EPS liner options, it offers an unparalleled fit. Its performance and finish place the Stream II among the leading choices in full-face motorcycle helmets.
