Is there anywhere in Australia that does wetsuit fit customisations? I have a good Kitesurf wetsuit that almost fits, except the neck is too loose for example.

I see they also do custom fitting.
The best wetsuit I have ever had was one that was custom fitted for me in Cape Town By Coral wetsuits.
When it final wears out I will get a custom fit again.
Just need to find a place that will do it for me.
