DRIMAC Winter Jacket Khaki with wool lining

I bought a Drimac jacket for my husband 18 months ago and it was hanging in the cupboard and when taken out this winter the zipper's "teeth" just fell apart - the jacket has only been worn 4 or 5 times. The zipper needs to be replaced but I dont want it to look any different than the original. Can Drimac assist please.
