One K Liners are the easy way to refresh your helmet or size up or down for a helmet that doesn’t quite fit.
The liners are removable and washable so you can instantly refresh your helmet.
The One K™ liner is made of a washable quick-dry fabric; it is moisture wicking and anti-microbial. Soak your liner in mild, soapy water and rinse it thoroughly. Let it air dry in the shade.
