I just feel more confident because a full face helmet is more enclosed, if I've got a dirt jumping lid on, even with goggles it feels better. However, I do find it harder to breathe with a full face and you get hotter in a full face but they are still the way forward for confidence and safety. Look at 4X, this decision is a lot more 'grey' because there is quite a mix of riders wearing full face and open face lids, all for their own reasons

I was one of the first people in this thread to moan about constricted breathing in a full face (based on an old MET Nitro). Well, I just got a THE One. It’s a bit hotter than an open face, sure, but it feels perfectly ventilated even at low speeds, and breathing is not an issue.

i agree i feel loads more comfortable in a full face than in a open helmet.

I just hate the thought of me knocking out my teeth or taking all the skin off my face.

Just like this guy

After falling from 10ft in the air straight onto my face and only have a minor fracture in the cheek bone and a tiny cut ive never ever thought full face helmets are daft. I owe my face to my full face helmet!

At Moelfre I could see the reason for guys not running a visor.. as bad as it looks with that kind of wind at the top it wouldve made a difference. The main trouble is the fact that the rearmost part of the visor goes straight onto the helmet, why not pop a few vents in there? Air could be directed straight into the venting system, or just to stop the inevitable wind catcher. I, like Aaron (pslide) would be interested to see a model of a TLD D2 (for example) in a wind tunnel..

Then again, had Stanny & Cathro got the gimp suits out they wouldve been quicker over the top field without doubt. I also noticed a lot of riders either wearing regular tops a bit smaller than usual or a few wearing lycra tops. Times are changing.

sorry for nit-picking but surely some pretty colours of a CFD'd model of a D2 would suffice?! Wink

any post/ undergrads fancy a bit of time in the computer labs modelling/meshing/ analysing this??

CFD?! Clearly i'm no expert Tongue

Just some kind of model to see how it affects aerodynamics?

Could be a good project for some uni student surely?

I know im a bit late but could the reason be crashes like Sam Dale's at the Fort Bill World Cup? I dontknow if you saw that crash but h managed to snap his face guard after the initial impact. Anything more open comprimises the structural integrity and strength meaning that it would have beens Sam's jaw and face only taking a slightly less powerful impact than it would have been otherwise.
