Weighing in at only 3.64 pounds, HJC introduces the CL-17 Full Face helmet designed for the every day rider. This lightweight polycarbonate helmet is both D.O.T. and Snell 2010 approved in sizes XSmall - 2XLarge. The CL-17 Plus sizes are D.O.T. approved and are available in sizes 3Xlarge, 4XLarge and 5XLarge.. The HJC CL-17 helmet has an advanced ventilation system designed to move the air through the helmet. The moisture wicking interior liner is fully removable, washable and replaceable. The HJC CL-17 also comes standard with an advanced anti fogging Pinlock Shield system to help keep your shield fog free during those early morning commutes. Offering many of the same features of more expensive full face helmets, the HJC CL-17 is considered one of the best buys at The Helmet Shop.
