First of all, the zipper only goes half way up.  Secondly, I thought I was getting a pair of tactical trousers in a shade of gray(charcoal), but I would describe this color as a shade of black.  In fact, I have black trousers that have been washed many times and are virtually the same shade of black as these trousers in charcoal gray.  Really dark, so just be aware of that if you're looking for a pair of trousers in charcoal gray
