What is Graphene? Isolated at The University of Manchester in 2004, Graphene is comprised of a single layer of carbon atoms arranged in a hexagonal lattice and is the lightest, strongest, and most conductive material ever discovered. Graphene helps absorb and retain warmth, regulating the body's temperature and aiding comfort during play.
