Get one that's the right size then. If it doesn't feel right then it isn't right.
Be aware of it and where your left elbow goes - assuming you are right handed. Balance what is worse, getting out or getting hit. I'm firmly in the former camp. Those who bat best with helmets are brought up using them. They are not easy to adapt to at a later age - at least not without implications to your form.
Guess there was a deleted post. Missed it :(
In no other season of cricket have I ever got injured whilst batting. I would not recommend wearing a helmet unless a) you've been wearing one since you were a kid and are used to it, or b) you're playing high standard of cricket with 75mph+ bowlers on hard bouncy pitches.
Well, having thought about this, I think I have blown it all out of proportion, I won't be facing anyone who will bowl that fast because:
A) I am usually middle to end in batting so I won't be facing the best bowlers
B) we are a village team playing 40 overs on a Sunday not the IPL or first class cricket
Apart from the youngsters in the team who have grown up wearing them, there is only one other in my team who wears one, and that is only because his brother it hit by the ball, thrown by a fielder trying to run him out.
Thank you for all your advise, friendlys start on Sunday so lets see how it goes this year 8-)
No hurry with the helmet. Just wait untill you get hit on the head and then buy one.
If anything, the place where you're most probably going to be hit badly is not in a game while batting, it's in the nets. Never, never, never get distracted in the nets, turning your back to the batsman while chatting to the other members is a too common mistake. And be wary if the nets are built right, I've been hit on the nose while bowling at the end of my follow through* by an on drive which came out as a lightning from the net at the side (there was a hole). Not really a pleasurable experience, let me tell you.
*careful also while bowling, keep focusing on the ball: return drives might be a lot worse than anything you'll face as a batsman
