HJC Helmets continues their IS (Internal Sunshield) series with the introduction of the IS-17. Like it's predecessor, the IS-16, the HJC IS-17 full face helmet includes the internal drop down sun shield. The sunshield eliminates the need to carry or switch over to a tinted shield. At any time, the motorcyclist can drop down the optically correct, UV protected internal sunshield to reduce glare. The HJC IS-17 weighs in at 3.31 pounds and is packed with features riders are looking for in a full face motorcycle helmet. This lightweight polycarbonate shell is designed to move air through the helmet and the interior liner is designed to keep the rider cool and dry. The rapid release shield system is easy to change out and is Pinlock ready to control fogging when needed.
