One K Skull Cap Helmet Liners CLOSEOUT

$ 26.00 $ 34.95

If a One K Helmet does not come in your size, you can easily change the liner for a perfect fit. Our liners also provide ultimate flexibility for growing children, shared helmets, or women who wear hair differently for schooling and show! 

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.
