Indoors is a no brainer for me, at those distances I always wear mesh but outdoor I usually don't wear anything. Outdoor I usually have a shemag around my neck. I bite down on it so that excess piles up in front of my mouth if I get in a close engagement.
I have the half mesh that doesn't cover your ears and I find once moulded to your face cheek weld isn't a huge issue. Had the full mesh first but it's so bulky that cheek weld is an issue even with moulding.
If you chose to wear nothing you're definitely taking your chances, I've had two very close calls oddly enough both at OP Rhino. 2011 I got a bleeder half on the lip and 2012 I literally caught a bb between my lips and had to spit it out.
