So, is this the reason Poc was known to have part of the helmet pop off in a collision? That was mostly with the race helmets a few years ago.
MIPS rotational violence protection
POC HAS ALSO ADDED the patented MIPS technology to our collection of innovations, aiming for safer helmets. MIPS is a system used to reduce the rotational forces on the brain in the case of oblique impacts. This is achieved by allowing a controlled rotation of the shell relative to the liner. We are proud to present this unique and necessary system in a bike helmet.
POC’s double shell helmets
TRADITIONALLY, there have been two different types of bike helmets on the market. First, there is the traditional hard shell helmet with a thick outer shell, covering a shock absorbing liner of EPS. The hard shell helmet provides good protection against penetration and makes a durable construction. But, the nature of the stiff outer shell also has its drawbacks.
ON IMPACT, the hard shell causes an abrupt stop of the head. This increases the risk of brain injuries. The hard shell may also bounce on the ground and thereby increase the risk of whiplash injuries. The second type of traditional bike helmet is the “in-mold” type. These helmets have a thin shell of polycarbonate molded together with an EPS liner. With this construction, the impact energy is very well absorbed as the thin shell allows the helmet to deconstruct on impact, creating lower energy levels for the brain to deal with and minimal bounce. The disadvantages are poor resistance to penetration and a less durable construction.
OUR EFFORT to combine the strengths of these two major concepts in ski helmets led to our patent pending “Aramid ballistic penetration barrier”: APB. By adding a layer of penetration-resistant aramid between the shell and the liner, the shell thickness could be reduced, leading to weight reduction and better energy absorption.
Transferring the APB concept into a fully ventilated system for bike users led to our revolutionary, patented Ventilated- Double-Shell-Anti-Penetration: VDSAP.
THIS CONSTRUCTION was initially developed for the Receptor+ all season helmet. A helmet certified in Europe and the US for: biking, skiing, snowboarding, skateboarding, and water sports. When developing the Cortex DH full face downhill helmet, it was an obvious choice to use the VDSAP concept.
VDSAP has two ventilated shells placed offset for maximum penetration resistance and channels in between the shells to ventilate heat, perspiration, or water. The inner shell is an extremely thin layer of polycarbonate while the outer shell is made of carbon fiber or injected plastic depending on model. The properties are amazing and these helmets represent an unique way of thinking in helmet design.

Still find it moronic that with all this technology and expense they can't hold my freakin' goggles on with anything other than friction.
