The fabric is unique. The pants fit large, so better to size down.

Just like many other say, this is a great pair of pants. Nice design, great quality. The only problem is you can not wear it.. Waist is toooooo big. I am 159lbs and 6ft. I ordered xs but the waist is still way too big. It is not just big that you can wear belt to adjust the fit. You have to tighten the belt a lot that eventually mess up the whole fit. Sadly but I have to return it. Adidas has been always one inch short from the best and this is perfect example.
