"When a zipper fails for me it's 100% a jacket." That's often so with me. I've an ex-NATO military jacket that I bought from disposals. It was new old/surplus stock so I am the first to wear it. It's by far my favorite jacket and it gets a great deal of use as it's not only excellently designed (in that everything about it is immensely practical), and that the quality of the materials used in its manufacture are excellent (it would be difficult to find better). Originally the military must have paid top dollar for them (and it's much better than the one my own country's military issued me with decades earlier). Nevertheless its zipper is a perennial problem in that it's hard to engage when I'm in a hurry and it often jams or is sticky at the start end. Fortunately, it has a large flap that covers the zipper from top to bottom and it is secured with a vertical row of buttons! I like that, there's nothing like a bit of 'bootstrapping' to guarantee things will always work.
