Black isnt all that bad. I love my luluLemon black sport jacket. Its not just good for keeping warm and wicking away sweat. Its tactically sexy and takes playing with style to the next level. Its not so good for blending in outdoors unless your playing at night, but indoors it doesnt really matter what you wear I guess. But Amos is pretty much has it right, mixing black and multicam doesnt really work all that well.
For my admin panel whenever I use a vest that has one, Usually mount two tap lights on the front. If you look on the side of my vest closest to my hand given the "OK" you can see one of the tap lights I used mounted to my vest. If I feel like mounting a patch its usually some band patch or a big pink suicide girls patch.
