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.
