The perfect fit for in-betweeners! The One K™ Defender Air Helmet** is the ideal helmet 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.

How can a One K Defender Air riding helmet be so adjustable? The secret is in the air pump system that provides the ultimate in comfort and custom fit. The three hidden air pockets in the liner inflate by depressing its concealed air pump until you get the fit you want.

The Defender Air horseback riding helmet features:

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

The One K collection of riding helmets boasts 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. Take a look at the full line of One K riding helmets to find one that perfectly fits your needs. All One K riding helmets are certified to ASTM standards.
