pend.) makes the line fall into place during the retrieve

The result is a helmet that not only breaks the mold in terms of looks but also in the safety and comfort departments

In practice, many of these existing technologies exert a force based on the amount they are compressed, leaving them prone to high spikes in reaction force when they reach maximum compression or bottom out ( In addition to being used for modeling of shock absorbing technologies, finite element (FE) modeling has been used to investigate brain injury risk and advance the state-of-the-art of helmet technology ( The objective of this research study was to use FE modeling to investigate the potential for a liquid-based shock absorber to improve the ability of American football helmets to attenuate the severity of both concussive and subconcussive head impacts in American football

also, some materials are cheaper to repair than others
