If it helps at all, I noticed a lot of tall men’s pants selections, including cargos, when I was making those links to Old Navy.
Cargo pants were fairly popular in the late 1990s-early 2000s. I worked for a company that specified they were not to be considered as business casual, we had to wear regular flat front khakis or dress pants on those days.
I don’t really care for the look, if you need to carry a lot of things, they’re fine.
Another cool aspect to the Tru-Spec pants is the elastic waistband. It’s hidden, and not the entire circumference of the waist - just a couple of bands on either side of the zipper.
Sooo, bending over, jumping, gorging at the buffet - you’ve got room to move and grow!
