Helmet Shapes - What's Right for Me?

• Regular/Round: head which has almost identical front-to-back and side-to-side measurements.
• Long Oval:  head which is longer front-to-back (from forehead to the back of the skull) than it is side-to-side (ear to ear).

WHAT IS MIPS?: Created 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.
