Shock absorbing, stretchable fabric, head cap for receipt under a head protection helmet

A light weight, shock absorbing, shock dissipating, moisture absorbing, stretchable fabric, head cap designed for receipt under a hard shell helmet and over a head of a helmet user. The head cap includes thin sheets of shock absorbing and shock dissipating foam pads. The foam pads are used to limit a shock load or pressure applied to the head. Also, the foam pads help spread the load over a large surface area of the head, thus reducing a potential head injury or potential concussion to the wearer of the head cap. The foam pads are received between a moisture wicking fabric inner liner and an outer liner. The head cap also includes a moisture absorbing head band and head band ties for securing the head band on the user's head.
