Where can I get belly putter grip?

Folks
Any idea which fitter has? Last time I search around in sg, I could not find and bot one from eBay. Now it is disintegrating(Winn grip la)

I'm looking for non Winn material. If u seen any in sg, pls shout thanks

Not in S'pore though

Thanks mate, but this is an extension to convert a regular length to a belly putter.
Looks like not many fitter stock belly putter grip...

Vinc Golf at Far East has grips for belly putters, not sure about the material though.

thanks mate, i will check it out
