Here's OMP's Grand Prix HANS helmet which many of my customers use. I also use it myself. Light-weight composite shell. Both SNELL 2005 and 2010 versions available.
• Narrow visor with high-precision adjustment mechanism that makes it fit very closely to the shell.
• Kevlar trimmed strap closure for greater safety and durability.
• 3 vents on the chin.
• 3 adjustable air vents on the shell.
• 3 rear vent holes.
• Hole to insert dringking straw.
• Removable cheek paddings (can be purchased separately also in larger or smaller sizes).
• Complete with HANS® safety device clips (replaceable for Hibryd® clips ).
