This is a tough topic.... In the market now:
Under Armour- Black, Khaki
Brooks Brothers Country Club- Navy, Black, Khaki, Light Blue, Red, White
Addidas- Navy, Black, White, Khaki, Grey
Tehama- Black, Tan
Cutter & Buck- Navy, Black, Tan
Callaway- Navy, Black, Khaki
Greg Norman- Black, Khaki
Nike- Black, Khaki, Grey, White
You get the picture... Lots of choices and a crowded market. That said, my current choices of Brooks Brothers and Addidas would change to FJ in a minute!
