I used my Ayrtek 12 vent on Saturday for the first time, firstly it is not a version that you can buy from Tom, he had a spare and I'm bigger than him and bought him beer in the bar under his flat.....
The lid is so very light, I have had mine in plain carbon fibre, with a little lacquer applied, looks stunning. The fit is better than my old Masuri as the shell seems to accommodate more head shapes and the only adjustment was to add the Titanium Albion grille from a sample Arytek to allow for my fat face. The helmet feels very secure with the lining pumped up, chin strap comfortable and well designed with the clip system.
I kept wicket on Saturday and wore the lid with our 2 "spinners" bowling in tandem on an interestingly bouncy wicket. I was able to hear and see very clearly as well as keep reasonably cool in the sun with no over on, over off scenario to fall back on.
Not had use for it batting yet but very happy after an unexpected first outing.
