If you can wear jeans to work you can try http://thunderboltsportswear.com/ they make one with black stitching.
It's the same material as the outlier OG, which is a balance of water resistant, stretch, and breathable
Same price too...however, I emailed them to ask when they would have my size, and since they did not have it the owner gave me 15% off.

They are a much slimmer fit than the outlier pants, about the same as slim fit jeans.
If you don't have big thighs they should work.

I have found cheap pants don't hold up so well to extended use
