ONE K Defender Refit Riding Helmet Liner

If your One K Helmet doesn't come in your size, you can easily change the liner to achieve a perfect fit. One K liners offer ultimate flexibility, making them ideal for growing children, shared helmets, or women who alter their hairstyle for schooling and shows.

• The Large helmet shell can be adjusted to fit an X-Large by using an X-Large liner.
• The X-Large helmet shell can be converted to an XX-Large with an XX-Large liner.
