It's a strange one. The thicker peak and fixed grille appear to be compliant, but the gap may not be.
Possibly a custom helmet for Cookie? But if anything did happen that would be a minefield
It may be a fixed grill new style( I cant tell from the pictures) but it's the gap that the issue is over. It def looks wider and more old style. That's really the crux of it...the gap to sight the ball. I know there's split opinion on this subject and ive posted a lot about it......the reason is I wear the grille same as cook and trott...there's a wide gap which a ball could techinically get thru but seeing the ball is the most important issue for me and im just an average club player.
It may be they have made a compromise with a fixed non adjustable grill just widened the gap. Hard to tell exactly until someone actually asks him-which i'm sure they will

don't think he likes social media thou so 'tweeting' wont work!!
