My brother bought this helmet as a present , when i first tried it on it was slightly loose and i still have to wear a wollen hat , this is to be expected especially if you have a pea head.
The quality of the Helmet is strong and would be hard to break. So far i've taken it down the pub where everyone tried it on and more importantly it survived the night (Unlike most things down my local).
If you like Star wars you will like this and not be disappointed
