The LS2 Stream II Helmet features an aerodynamic, sport-styled shell made from LS2’s proprietary Kinetic Polymer Alloy (KPA). KPA uses nanotechnology to blend microscopic aramid fibers with a high-end polymer and allows for amazing energy-managing performance with managed flexibility that absorbs energy without the ricochet effect of inferior materials.
