Replying to Why North Face is amazing

I have this north face "exetreme" jacket that has been passed down through the family. This thing is awesome it must be at least 30 years old and it's still holding well.... Or at least until this weekend where after 3 decades the zipper finally broke on it and now I have no idea what to do with the jacket cause it's sick and was my dads it and I don't know anywhere that would know how to fix it since it's so old thanks for any advice ns
