The zipper pull on my raincoat broke off and a few teeth of the zipper also broke last year. With cooler weather on the way I'd like to get the coat in shape again. The zipper is the large plastic type with thick teeth. It's approximately 27" long.

Does anyone know a good source for this type of zipper, and do they come in standard lengths? Are they easy to find anywhere? It doesn't need to be plastic, but it does need to be navy blue and durable.

Thanks for your help,

Jen
