What is KPA?

LS2 Helmets created their proprietary helmet shell material Kinetic Polymer Alloy, (KPA). It uses nanotechnology to stretch and shrink aramid fibers down to where cross-sections are about 1 BILLIONTH of an inch thick and then encases them in a high-end polymer. You essentially end up with an aramid fiber shell encased in polymer. This video explains how KPA might be the best material ever developed for building a helmet shell. KPA tests as well or better than the best of the best traditional composites. It's lightweight, has some designed-in flexibility for energy management, and has a penetration resistance that meets or exceeds the best known composites in the world.
