The 2nd Skull® Pro Cap is our newest product that was engineered with a $100,000 grant from The National Football League and has improved capabilities over our original 2nd Skull® Protective Skull Cap. Testing under the keen eye of the NFL proved the Pro Cap is in the same heat index category as any skull cap/wrap that offers no impact protection.

The Pro Cap is designed to fit comfortably under any helmet, or as a stand-alone in non-helmet activities. When paired with a helmet, the new material on the Pro Cap adds extra slippage upon contact. Biomechanical testing proves that the more the helmet can rotate on the cap, the less rotational force put on the player.

It features thin, 2 millimeter XRD® impact-absorbing technology for superior protection. The thin profile makes helmet fitting a seamless experience. The material is flexible at rest, but can instantaneously harden under sudden pressure, thus helping to mitigate the effects of sudden impacts. The moisture-wicking fabric offers a comfortable fit that conforms to your head while keeping you cool.

2nd Skull® provides game-changing protection against impacts and has improved the performance of all helmets it has been tested with. Focus on your performance and reduce the risk with the 2nd Skull® Pro Cap.
