OK, I'm hoping the folks on this board can help us.

We're looking for a GOOD quality, long sleeved, medium weight cotton, perferably two pockets with NO flaps, in solid colors, shirt. Not a heavy Pendelton type but good quality. It will be used in a business setting (as a type of uniform) with average temps of 50 - 70F. Not stuck on it being cotton but that is the type of look we want.

Any reliable source is welcome.
