Safety For The Whole Team!The Fire Retardant Pit Crew Helmet from RaceQuip features a comfortable open face "shorty" design that easily accommodates a radio headset. Over the wall team and fire safety crew members prefer these helmets because they are built just like the RaceQuip driver's helmets. They utilize an FRP (fiber reinforced polymer) shell, an eps (expanded polystyrene) impact liner, fire retardant blended Nomex® interior, and a special fire retardant exterior paint. An ABS visor runs across the front of the helmet to reduce glare from the sun and exhaust vents allow airflow across the scalp to promote cooling. The multi-point adjustable webbing system makes the this helmet very easy to adjust and comfortably attach to any head. Since these helmets utilize headset clearance cutouts around the ears, they do not meet the specifications set for Snell or DOT ratings.
