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

Helmet Shape:

  • Regular/Round - Is shaped for a head which has almost identical front-to-back and side-to-side measurements
  • Long Oval - Is shaped for a head which is longer front-to-back (from forehead to the back of the skull) than it is side-to-side (ear to ear)
  • Fitting & Adjustment

    The One K helmets are available in 3 shell sizes. By using the One K foam liners you can achieve the perfect fit. This system allows the helmet to grow with the young rider. One K helmets are available in 2 shapes, Regular and Long Oval which emphasizes an elongated head from front to back and slightly narrower measurement from side-to-side.

    Wearing the wrong shaped or size helmet can lead to increased pressure and discomfort. One K has options for perfect the fit. Please note that both Regular and Long Oval shaped helmets use the same liners. Shape is determined by shell, not the liner.

    One K Refit Liners
