There's only one button, not sure the mic will have enough room to go that way along with one of the body cams (we have L3 cameras and the Taser ones as well, you may get a different one each day) as they are different sizes.
I'll play around with the placement when I get to work Monday night and see what I can come up with. Put all my stuff on with the different uniforms and made sure I can still reach my pouches, radio body, mic, etc. with ease, and ran the mic cord from my left hip up and around my right shoulder, down to the center of my chest.
If I keep doing it that way, a Mic Loop should be all I need to keep it 100% secure vs. the left hip, under the armpit and up to the center of my chest route I'm using now. Lost my whole god damn radio (came out of the pouch) in a foot chase about a month or two ago and had to double back for it, but my mic is always the first thing to go whenever I do anything faster than stand up it seems. Our class B shirts are the zip-up version with faux buttons. I might need to reinforce them before I hang anything off one of 'em. I've been dealing with that aggravation for two years and never did anything about it but I think now is the time.
