Arai Signet-Q Hydra Helmet

The Signet-Q takes all the favorite features of the RX-Q and create a whole new series based on all the successes. On the outside, the Arai Signet-Q Helmet looks very similar to it's namesake, the RX-Q, but on the inside you can see and feel the difference. A longer shell shape on the Arai Signet-Q Helmet gives 5mm more space front to back allowing for a larger number of heads to fit comfortably. The shape of the Arai Signet-Q Helmet releases forehead pressures and eliminate hot spots for a more comfortable fit every time.  This shape works best for riders with a long oval headshape.

Additional Features of the Arai Signet-Q Helmet

  • 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)
  • Long Oval Fit
  • SAI "MAX-Vision Brow Vent" shield
  • Clear Pinlock Max-Vision Brow Vent Pinlock lens included
  • Elongated shell adds 5mm from front to back
  • Long-Oval shape helps prevent “Hot-Spot”
  • 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

Best helmet Been riding for over 30 years so I've owned many helmets. Most of them have been Arai's. This one is by far the best. August 26, 2014
Awesome Helmet, and Sick Graphics!!! This Helmet is Fantastic! The graphics are sick. The helmet fit my head perfectly right out of the box, but i was amazed with the helmet's fine tune ability. The helmet has lots of vents, and it keeps pretty cool. All my friends are amazed at how light the helmet is compared to theirs. Overall I do recommend this helmet. It might seem a bit on the pricy side, but you can't but a price on your life. August 4, 2014
Long Oval Heads, Rejoice! Bought this because I have a long oval head shape and the vast majority of helmets don't fit me. This one fits perfectly. In fact, now that I have it, I realize I never had a properly fitting helmet before! I've had a few that caused pressure points, and a few that were loose. This one - perfect. It doesn't feel tight, and it doesn't feel loose - it's just right. Other than that - noise level is less than my previous helmet, but still quite a bit of wind noise. Visor is crystal clear, gorgeous. Thoughtful vents. Arai quality - all you need to know really. About the design - this helmet, like most Arais, looks much better in person than on the pics. It's drop dead gorgeous. July 4, 2014
