AKA "zipper plow" or "anti-snag zipper cover," they're on many new jackets and sleeping bags.
Does anyone know where I can get some of these? I've been looking for many hours over the course of several days.
I have some jackets with the exact required zipper sliders but they don't have the cover and all the snagging is hugely annoying, ESPECIALLY when I'm wearing gloves.
Note they don't work on aquaguard zippers which are reverse coil... but they should work on non-aquaguard reverse coil zippers.
Cool idea though looks a bit bulky and I'm not sure that it would work for separating zippers as on jackets.
They also specify that you need the appropriate spacing of the zipper from the fabric of the item, which in your case you can't control, its already been sewn.
