Shoei Neotec 2 - Breather Guard

[Capt Sisko]

A question to Shoei Neotec 2 owners. Does your Breather Guard keep falling out?

I'm on the point of ditching mine completely as it seems to come loose then out at the lightest of touches, such as catching it whilst push back my glasses when wearing thicker winter gloves. I've tried basic UHU type glue but the fit is so loose I'd feels like I'd have to apply half a tube of the stuff just to fill in the gaps and I don't want to use a permanent glue like Araldite or a heat gun glue. Looking at Shoei's website there is only one breather guard so it can't be a 'you've got the wrong size' issue and no matter how far, firm or otherwise I press it in, sooner rather than latter it comes loose.

So, do others find theirs coming loose or is there a secret technique to securing them in place?
For clarification it's the bit arrowed in the photo below.

Mine fits and the only time it came loose is when I picked up the helmet by the chin guard and dislodged it. Clipped back in and stays there.Not sure why yours wouldn't? I'm assuming the ends are slotted into the small slots in the chin guard?

I never bother having it in.
