Sena Momentum Inc- built in communication system. Never worn. I have the same helmet in black. Love it! Got a new Schuberth also with built in communication before I got a chance to wear this one, so no longer need this one. Never dropped, barely ever out of the box. Got it on sale a GP Bikes for 650.00 but can’t return it because it was on sale. May be able to deliver depending on your location. Size M.
