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!
