I have two pairs of the Cabela's cargos, one in charcoal gray the other in dark green. They're very well-made, very warm (but can be worn up into the 70s without being uncomfortable) and fit true-to-size.
One thing I like about the cargo pockets is that they're actually useful and they don't use a 'requires two hands to operate' button or a 'makes so much noise you might as well go back to the truck' velcro closure, it's just a simple 'nipple' snap button that isn't very loud but stays closed and is easy to operate with or without gloves on.
My only complaint would be the colors are darker than I prefer; I'd prefer a field gray to a charcoal gray and a more olive green than the dark forest green as it worries me that the darker colors are standing out too much when hunting rather than blending into the environment.
