The 2nd Skull Cap is designed to fit comfortably under any helmet, or as a stand-alone in non-helmet activities.
It features thin, 2 millimeter XRD impact-absorbing technology for superior protection. The thin profile makes helmet fitting a seamless experience. The material is made from special urethane molecules that are flexible at rest, but can instantaneously harden under sudden pressure, thus helping to mitigate the effects of sudden impacts.
