Cortex is a generously ventilated full face helmet with a durable fiberglass outer shell. The liner is made of multi-impact EPP, which means that the helmet withstands numerous impacts. The open vents allow more air to flow through the helmet, increasing the user comfort and functionality.
Most helmets today have liners made of EPS (Expanded Polystyrene), a great shock absorbing material, but it will be permanently compressed when absorbing an impact, even a minor one. Using multi-impact EPP (Expanded Polypropylene)as core material creates a helmet that will protect your head over and over again.
