LS2 Copter Helmet The LS2 Copter Helmet has a unique aerodynamic three-quarter length shell. Mirroring the drop-down internal sun visor is a quick-change face shield that features extended coverage and a unique wind diffuser along the bottom edge to reduce turbulence to the rider. Oversized brow vents boost airflow - even at slow, urban speeds. These contrasting vents contribute to the unique styling of the Copter's wind tunnel-honed shell. Sporting a ratcheting quick-release closure, the Copter Helmet is a friendly companion for quick city jaunts, winter glove weather or mornings when you just don't want to take a hand off of that espresso.
