Faulty zip on leather jacket

[greenie1981]

Ive just recently bought a leather jacket and the zip keeps coming apart while im riding.
I've taken it back to the place and they would exchange it since I've worn it. They can have it sent away but I won't get it back until the new year. They ended up taking it to a dress maker who is apparently changing the zip. Do they have to be a certain zip or can it be any kind of zip being a zipper for a motorbike jacket?

I doubt that there is an industry spec on the zip, but the better units will use a fairly heavy duty unit. My Texport set of leathers use YKK zippers. My old Dainese set uses OPTI zippers. I would think a dress shop or tailor would supply a decent one.
