(± 25 gr.) IPX® Acells – the helmet inpact absorption technology The new helmet impact absorption technology from O’ Neal is designed to reduce head injuries caused by low speed & rotational impacts during crashing. The IPX® Absorption Cells (ACells) use a specially engineered polymer foam, developed to make O Neal s helmets some of the safest on the market in the event of a crash. IPX® ACells are positioned on the EPS (expanded polystyrene) liner on the inside of the helmet in small recesses, between the EPS & the comfort liner. Every part of each individual IPX® ACells has been specifically engineered to work together to provide the ultimate in crash protection. Race-Ready: IPX® ACells do not affect the fitting of the helmet liner. Helmets with IPX® ACells do not bounce or move on the head during riding. Enhanced-Forehead-Protection: The positioning of IPX® ACells enhances the performance for direct or oblique frontal impacts, using lots of individual components & positioning them more towards the front of the helmet. Note Please be aware, as long as nothing else is written in the item description: All helmets will be delivered only with the ECE certification by default, even if it is shown differently. all helmets that have a visor will be delivered with a clear visor, even if it is shown differently.
