POC's Cortex Flow is a generously ventilated full face helmet with a durable fibreglass outer shell. The liner is made of multi-impact EPP, which means that the helmet can withstand numerous impacts. The open vents allow more air to flow through the helmet, increasing user comfort and functionality.
The Cortex Flow Helmet features ear chambers that have been designed for less effect on balance and hearing while the chin bar has been constructed for optimised protection and easy breathing.
Multi-Impact Performance: To date, both traditional hard shell and in-mould helmets have relied on Expanded Polystyrene (EPS) for shock absorption. EPS absorbs energy by plastic deformation on impact and results in permanent deformation. As a consequence, a helmet liner made of EPS will not be as good at absorbing repetitive impacts. Most of POC’s bike helmets use a liner of Expanded Polypropylene (EPP) instead of the traditional EPS. The difference between the materials is that EPP does not deform permanently, which means it’s suitable for absorbing repetitive impacts.
