This is the deal with a Masuri or Albion, most people just use the chin strap as an after thought.
i must have a big head lol cos only have to pump it up like 2-3 times..the problem is the air cussion system is like memory foam it will mold to ur head..it feels awfull at first but after a few nets games its snug as a bug in a rug
I haven't used my Ayrtek in the nets or in the middle yet, but I have tried it on several times. One way that I found to get a better fit is to hold the helmet down on your head with one hand, while you work the pump with the other. This prevents any tendency to ride up if overinflated etc. (perhaps I've got a pointy head?).
Doesn't sound like you are using it properly. Put the helmet on, do the strap up tightly and then inflate the ACIS system. Haven't had a problem with doing it like that.
Are you securing the chin strap under your chin, with your chin in the cup (and not behind it) properly?
Liam, or Tom, I've stuck the pads in and it's such a comfy helmet! However the glue on the Velcro strip isn't sticking well. What glue did you use Liam, or Tom what is the best glue? Don't want to damage the ACIS
