I recently purchased a jacket that had an unusual feature; a zipper with a spring on the puller. A quick Google search made me realize that this spring loaded Crown zipper was a desirable feature for which people paid extra. This made me realize; I really have no idea what people look for in a zipper, or why people prefer certain brands if zipper. I do know that I consider hookless zippers to be a menace; I've almost become entrapped in a jacket a couple of times due to these, and I've broken one on a real mccoys. But what do people here value in a zipper, and why would you pay extra for a particular type? Other than the hookless are some more prone to failure? Thanks
