If this has been covered elsewhere, please direct me there (and I will update or delete this) but: How do you don and doff a PC correctly?
Asking because wearing it high enough means your head sorta barely fits through the top so you go slow, bang your head, knock your glasses off, etc. My experience (reinforced with some asking around) is that people avoid that, and after a bit re-adjust the PC to wear lower for easier donning/doffing. Not lazy or stupid, but all in the name of being more effective, so they can react to situations faster, despite the end result being less optimal armor coverage.
Is there a trick we're all missing? Or at least a mod/upgrade like shoulder straps you can leave loose but which can be tightened up once on?
