Although they are simular they are by no means the same. i participate in both sports and have separate equipment for both, honestly if your just playing for fun one in a while then you night not see a real difference worth the price.
Hmm used to wear masks with straps... Then a bought one that didn't come with one... Guess what happened, nothing happened any different. Ive never had my Grillz fly off, with or without visor. But i have been forehead shot without the visor on before lol.
They are not necessary or else all masks would have them right? everyone has their own personal safty preference. some wear masks without straps and others wear straps and full body tabs with chest padding... personal preference is all
