HOW THEY DIF­FER FROM EX­PEN­SIVE LIDS

Motorcycle News (UK) - - Garage -

Most en­try-level hel­mets have a ther­mo­plas­tic outer shell cov­er­ing the poly­styrene EPS be­neath. More ex­pen­sive hel­mets still use poly­styrene cores but the shells are usu­ally made from fi­bre­glass, or a com­pos­ite of fi­bre­glass, car­bon-fibre and Kevlar. Fibre shells can ab­sorb more of im­pact, mean­ing the EPS has less work to do.
