The LS2 Stream II delivers style, features, and performance that surpass helmets costing twice the price. Built from LS2’s proprietary Kinetic Polymer Alloy (KPA) with A.R.E.M. rotational energy management, a rear spoiler for dynamic flow-through ventilation, and a Pinlock-ready Class A shield — this is an out-of-the-park value in full-face motorcycle helmets. Available in Gloss White, Gloss Black, Matte Black, and Gloss White/Blue/Red.
