20 year old Patagonia ski shell

The zipper tab on the front zipper of my all time favorite ski garment is finally wearing out. Now mind you, this thing owes you or me nothing, as it's done me proud on many a trail and mountain.

I can still zip it carefully, but's days are numbered.

The jacket is medium purple/dark purple, shell style, with chest pockets, velcro sleeves, and a permanent hood. It has a waist bungee, and it fits me better than any other I've tried. Brilliant.

So, please - can you fix him? Now that I think about it, it dates to the 80's - Brick Wheels in Traverse City, MI.
