I have a down jacket that I ripped the zipper on. I made the mistake in cutting the zipper along with the length of fabric that it was attached too. I now have a 300$ pillow. Hook and loop would wear out. Buttons maybe reasonable. Snap buttons too. I'd hate to ruin the jacket anymore than it is just looking for some ideas if anyone has any. I usually will wear it under a shell so it just needs to close up enough that it's still usable and of course won't be too much of a problem if I'm wearing a pack in the morning with it. Maybe you can help. Thanks.
