Headgear problem
 

Please, I bought a headgear that's slipping up a lot. I really don't understand why because it's really tight, and there's some headgears in my gym that are not that tight but don't slip at all.

It's a big size headgear, this Petrorian one http://produto.mercadolivre.com.br/M...tam-grande-_JM (it's on portuguese but you can see the pictures)

The product is awesome but this problem is just ruining it. Every punch he slip upwards and I can't see.

I want to know what's wrong with this. Should I have bought the medium one? The design is the problem? Or should I keep using it and he'll adjust to my head's shape?

Or should I just try to sell it and buy another one?

Hope you guys can help me! Thanks!

Instead of saying "get used" just say "adjust"

Thanks, edited.

I had one similar to this and it did used to slip also, I think because of the material when it gets wet. Personally I preferred it slipping now and again as it takes the power out of the punches rather than transferring it to your head.
