Arai Signet-Q Helmet (One Left Diamond Grey Medium)
- Slightly longer front to back length than RX-Q for true “Long Oval” fit; elongated shell adds 5mm from front to back
- Long-Oval shape helps prevent “Hot-Spot”
- Both the top vent set and side exhaust cowls are direct carryovers from the RX-Q
- Brow vent ducting redirects to flow air across the temples
- DDL-4 exhaust vent to the 10mm wider eye port (5mm on each side)
- SAI Max-Vision “Brow Vent” shield
- Clear Pinlock Max-Vision Brow Vent anti-fog lens included with the helmet
- Multi-density single piece EPS liner
- Removable, replaceable, washable interior
- Dry-Cool Surface material for rapid displacement of heat and moisture away from your head and into the ventilation airflow for added comfort while riding and a quick dry between rides
- 5mm peel-away temple pads adds another level of customization, giving the helmet interior a little extra width when needed
- Enhanced for customizable micro fitment interior without the need to purchase extra interior components
- New FCS (Facial Contour Support) cheek pad design
- Innovative and exclusive spring support adds just the right amount of pressure when needed while being worn
- Meets or exceeds Snell and D.O.T. standards
