Looking at all the shirts, I like the Condor Outdoor Short Sleeve Combat Shirt, and the Condor Outdoor Combat BDU... Also, I can get those in my big boy size...
Anyhow, if they do come in black, I'd say go with that, but I'm open to the OD also. I just think that the black makes for a cleaner dress unit, especially when going for the 'team look'.
If we go for a full outfit, I do like that choice you put up! Just gotta make sure they have big boy sizes :)
