A protective cap for protecting a brain within a head from concussions and brain injuries commonly associated with sports or assault is provided. The protective cap comprises a cap having an outer surface and an inner surface. The cap is constructed from an aramid material and conforms to the shape of the head and snugly fits the head. The cap provides a lightweight, comfortably fitting, safe, effective, and discreet means of protecting the head from impact.

A brain injury reduction system provides a protective measure that temporarily or decreases venous drainage out of the intracranial compartment during or immediately before and during a sudden change in acceleration of an individual's head. Specifically, a wearable helmet or other wearable structure of the brain injury reduction system detects an impending collision and determines whether a protective measure is needed. If so, one or more actuation devices provides the protective measure to reduce venous drainage through one or both of the internal jugular veins or paravertebral venous plexus. A first actuation device stimulates a gag reflex or valsalva-like maneuver to reduce venous drainage through the paravertebral venous plexus. A second actuation device can physically compress the internal jugular veins. Thus, the brain injury reduction system minimizes the detrimental impact that may occur due to the sudden change in acceleration of the individual's head.

A face guard is disclosed herein. The face guard is configured for a human user having a face with a mouth and nose. The face guard includes a mouthpiece configured for retention in the mouth of the human user. The face guard also includes a face mask coupled to the mouthpiece, wherein the face mask configured to cover the mouth and nose of the human user.

An impact-attenuating liner for a helmet includes a liner body made from an impact-absorbing material and a plurality of pads removably attached to an interior surface of the liner body, each of the pads being repositionable at different locations on the interior surface of the liner body. A retention system may be attached to the liner body and configured to secure the liner to the wearer's head during use. The liner may be configured to provide substantially uniform impact protection throughout the interior region of the helmet.
