You may not be able to fix this with our Zipper Rescue Kits,
If the damage spot is up near the top of the jacket, visit FAQ #2 linked below.
If damage is in the middle or near the top, sewing skills and a brand new zipper are the only real fix.

Before you give up, watch our Instagram video explaining how to sew in a new zipper without unstitching the old one.
Saves a ton of time and requires much less skill, could even be stitch it by hand if you have the time..
