The One K™ Defender Air Helmet** offers the perfect fit for riders who are in between helmet sizes. This is a good choice if: 

  • Your head is not exactly round, nor exactly long oval!
  • You are between standard helmet sizes, or just plain hard to fit.
  • You like to adjust the fit of your helmet throughout the day.
  • You sometimes wear your hair up, other times down.

The secret to this helmet′s adjustability of fit is the air pump system that provides the ultimate in comfort and custom fit. Three hidden air pockets in the liner inflate by depressing its concealed air pump until you get the fit you want.

This Defender Air horseback riding helmet features:

  • Matte Polycarbonate and Advanced ABS Composite outer shell.
  • Injection molded shell design.
  • Quick-dry, moisture-wicking, antimicrobial liner.
  • Stainless steel mesh.
  • Comfort padded harness with synthetic suede lining, hook-and-loop adjustment and Fastex buckle.
  • Two side, two front, one back and two center stripe vents.

One K riding helmets boast the perfect synergy between advanced technology and aesthetically pleasing helmet design. With enough features to appeal to those seeking everything a riding helmet could possibly offer, wrapped in a package that traditionalists can appreciate, One K has the best of both worlds. **ASTM F1163-15/SEI Certified.
