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.

The Jr helmets feature a smaller internal helmet diameter, a thicker padded liner, and a smaller chin strap which is 15mm shorter in length than the adult sizes!

MIPS: Founded in 1996 by a neurosurgeon and a researcher from the Royal Institute of Technology in Sweden, the Multi-directional Impact Protection System (MIPS) is designed to add protection against rotational motion transmitted to the brain from angled impacts to the head. Rotational motion is a combination of rotational energy and rotational forces from angular acceleration that both increase the risk for brain injuries. MIPS’ added protection has been independently proven to reduce rotational motion by redirecting energies and forces that would otherwise be transmitted to the brain. Data and info provided by MIPS.

This helmet is available in the standard round fit, as well as the "long oval" fit. If your head is a bit more oval, or if you have a lot of hair to put up, we recommend trying the long oval.
