I have been using the POC Cortex DH full faced helmet for several months now, and it has been comfortable, durable and safe. The helmet offers a plethora of protection and features, which are all engineered with safety in mind, and my crashing and tumbles have shown it to be an ideal candidate for the wicked world of rocky gnarliness and speed.
The Swedish based POC company was predominantly a snow sport protection company, and they have always had safety at the forefront of their research and technology. They have recently morphed over into the biking protection world, and their full faced Cortex DH helmet is their epitome of safety standards. The POC Cortex DH uses an innovative 2 layer shell, a lightweight carbon fiber wrapped around their aramid (aromatic polyamide) reinforced in-mold liner. The liner has a thin shell of polycarbonate covering the multi-impact Super EPP (expanded polypropylene) core. The double overlapping shell design, uses their VDSAP (Ventilated Double Shell Anti Penetration), allowing a fully ventilated construction with maximum comfort without sacrificing penetration resistance or impact energy management. The helmet will eventually be equipped with the patented MIPS system to reduce the rotational forces to the brain in case of an oblique impact.
Wow, that is a head full of techno babble, but when it comes to safety, and especially with my noggin, I am all for it!
The chin bar size and distance have been optimized for protection, without sacrificing breathability. The Cortex DH has a plethora of vents, over the top, the sides, under the visor, and next to the ears. They have something they call “Ear Chambers”, which are designed for increased equilibrium, balance, and ability to hear better on the trails.
