Odilinksi: forgive me, I'm useless when it comes to anything techincal (even a 2-piece helmet..) it holds up surprisingly well, and though the guard is made up of two pieces (joined together at the tip) it's pretty sturdy, especially from straight on. It certainly does flex a bit though if you put one of the sides between your finger and thumb and bend. The one thing that makes you worry a wee bit is because it's attached by four screws, it makes you wonder if the thing would ever just shear off the entire chin guard if you ever gave it a proper whang.. but I'm pretty sure if I ever subjected it to that kind of force, I should be wearing a proper full-face already..

I think you’re staring from a fundamentally flawed assumption “Pslide”, that being, current MTB full facers aren’t designed for DH riding which of course they are, and it has been/still is an evolving design process…
The TLD D2 has been the example pointed to over and over, but other helmets all share common features, primarily increased enclosure of the head, a structurally integrated chin guard specifically designed to absorb and dissipate frontal impact and a visor (serving whatever purpose people think, I always thought it was meant to help shade your eyes from sun glare)…
But basically protection comes way above ventilation on most riders list of requirements from a helmet, if you can improve comfort without compromising protection your onto a winner, my suggestion would be stop drawing Nova body kits, and start actually thinking about airflow, there’s more to it than peppering every surface with holes…
Downhill racing has some quite horrible design requirements for a helmet, we cover the lump on top of our bodies where a lot of our thinking is done, and where we radiate more heat than any other area of our bodies in 2” thick insulation and then go for what is essentially a flat out sprint requiring lot’s of concentration, from a slowly cooking brain… finding a way of keeping your whole head cooler for just one run, or even a whole days riding would be a massive leap forwards…
Nobody’s saying current helmets are prefect but they certainly aren’t bad and the re-breathing issue to me seems to be an imagined one, sure it happens when your stationary, but above 4Mph I would imagine the airflow through the forward area of even the cheapest helmet means your exhaled breath is carried almost straight off…

isn't the visor meant to take the first blow when you crash??
