Don't let the ride end just because you're riding in the dark. This light emitting diode (Led) helmet is here to keep your head safe while keeping you visible, so you can focus on the road ahead. It's got a reinfo remote controlled acrylonitrile butadiene styrene (Abs) shell and shock-acrylonitrile butadiene styrene (Abs) orbing expanded polystyrene (eps) core, so it can take a hit and keep you protected. Plus, it has a built in size adjustment dial so you can get the perfect fit each time. And when you're done with your ride, just pop off the earpads and inner fleece liner for easy cleaning.
