Hugo Boss Athletic pants

These are fantastic athletic Hugo boss pants. I am 6 foot 170 pounds. You can look at the video and the photos to see how it looks on me. They come up past the ankle and have zippers down at the bottom. Tag says size 36 but I find this hard to believe. I’m a 31 waist. I mean I do have to tie them tight to fit but I bet these will fit between 32-36.
