So I am reading in the IDPA Rule Book that "Targets may be covered with clothing as desired" but don't recall ever seeing this in IDPA match videos or any of the few matches I have shot? 4.10 does specify that the material has to be lightweight and I wondering if the shirt, t-shirt (sweatshirt?) would need to be changed out a few times during the match and perhaps should be identical?
I actually like the idea from a realism perspective if the clothing does in fact minimize or completely eliminate the visual confirmation of hits on the targets, which could add an interesting dimension if deployed in conjunction with a limited stage? I suspect that dark material would perhaps be more effective at masking the hits, especially if the target is at some distance?
