The RZ-34 is the ultimate cooling helmet, and now its offered in youth sizes! The RZ-34 is constructed from heavy duty, lightweight fiberglass shell. This helmet also features multiple chin and scalp vents for superior cooling, and contains that 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-34 also features a super plush, fire retardant lining, replaceable face shields, and tear-off posts. The lining has radio/hydration cut-outs in the chin. Every RZ-34 helmet comes pre-drilled for head and neck restraints.
