The idea is a full face helmet that doesn’t come off under impact, yet is easy to remove after impact. The end result is strapless — whilst still fitting better than traditional helmets.
Modern bicycle, ski, snowboard, skate and motorcycle helmet construction hasn’t changed significantly since the adoption of styrofoam impact absorption in the 1960s. Finally, new materials and construction methods are improving safety, in some cases absorbing 30 per cent more energy than their styrofoam equivalents. And you can buy helmets made from them today.
