Zamp's RZ-37Y Youth Racing Helmets are constructed from a lightweight, heavy-duty fiberglass shell and feature multiple chin and scalp vents for superior cooling. The RZ-37Y helmet contains a 7-Top Air System for even more cooling capabilities. The 7-Top Air System is a special air scoop on the top of the helmet that has seven holes in it, providing extra cooling above and beyond standard chin and scalp vents. The chin spoiler on the helmet makes these helmets better suited for open cockpit driving. The RZ-37Y also features a super plush, fire retardant lining, replaceable face shields, and tear-off posts. The lining has radio/hydration cut-outs on the chin. Every RZ-37Y helmet comes pre-drilled for head and neck restraints.
