The LS2 Stream is a full face motorcycle helmet with a built-in drop-down smoke sunshield, so you can cut glare without swapping visors. The tricomposite fiberglass shell carries both DOT and ECE certification, and the clear visor is Pinlock-ready with tool-free quick release. It suits commuters and touring riders who want a sunshield and a long oval fit. Against rivals, it offers the sunshield and Pinlock prep at a level where many helmets charge extra for those features, but it is a fairly heavy helmet and the single shell size means fit varies by head size.
