not worn a lid keeping since under 17's
restrict your view a grate deal specialy when balls goes up in air high.
I used to be like that. As soon as I was old enough I stopped wearing a helmet to keep. I used to think that it impaired vision, and was hampering my game, but that's all nonsense in my eyes. It was more of an excuse! haha
I use a Masuri titanium for keeping and it's fantastic. Does exactly what it says on the tin and I now hardly ever notice it. Although at the best part of £100 is a little pricey.
The thing about standing up to medium pacers is that you can do everything right, but if the ball bounces strangely off the wicket, or a batsmen nicks a quick one it could easily hit you in the face and causing massive damage.
