my black sheath on the 14 pro always had
my black 14 pro sheath was a mess along with crap buttons but this grey sheath is perfect no dirt buildup and perfect everywhere else except for slight misalignment which caudabe said they are sending over a replacement for hopefully its fixedI noticed this with my Sheaths over the past few years. My theory (it’s just a theory) is that the rough surface acts as a kind of sandpaper that lightly abrades the skin, which builds up over time causing the gray haze.
