Although it may look unassuming, the Pit Boss is anything but a rudimentary cruiser helmet. With a removable neck curtain, internal sun shade, and comfortable fit thanks to the adjustable Speed Dial fit system, this lightweight helmet offers heavy-duty capabilities. Perfect Your Fit Looks can be deceiving. At first glance our Pit Boss may look like many other half-helmets in the cruiser category. Scratch the surface, though, and you'll discover quality that sets it above the competition: A lightweight TriMatrix (carbon/Kevlar/fiberglass composite) shell, an innovative Speed Dial fit system that prevents the "lift and slippage" plaguing most other half-helmets, a drop-down internal shield in Dark Smoke that provides on the fly protection from the sun, and a removable neck curtain offering cold weather protection and speaker pockets for a convenient way to add audio enhancement. Snug the Pit Boss onto your head and thumb the starter button - one ride will confirm the Pit Boss as the King of the Road. Availability, certification, color, and pricing may vary per region. If outside of the USA, please check with your authorized local dealer for more information.
