I agree, driving by and seeing a crew working in a uniform says positive things about the company. Yes, khaki pants look better and will be cooler than green. Dark green was one of the colors that did "very well" when they were testing the early home made solar collectors, since it absorbs certain frequencies. Don't ignore the outdoor market, the modern materials are tough. The new nylon type pants are breezy in the Florida heat.
I'm not sure if it would make sense or not, but does anyone use the pants that zip off into shorts? This is one company that deals with closeouts, campmor.com is another.
