Bests & Worsts Reviews from Amazon

I bought these pants in "The Rich - Stretch" and "Rigid Dragon - Stretch" colors, same size. I chose these two colors in part because they are listed as having the same blend of materials, which is confirmed by the tags on the pants as 99% cotton, 1% spandex (you'll notice looking through the descriptions that some of the "colors" of 541 on here have very different blends). So here I'm getting two "colors" of what should otherwise be the same pants - same 541 cut, same 31x30 size, same blend of materials. That is not what I got. "The Rich - Stretch" fit exactly as I was expecting - a comfortable amount of room in the seat and thigh but not loose fitting, tapered at the bottom of the leg so it sits well on running shoes (the reason I chose the 541 cut over others). "Rigid Dragon - Stretch" fits very differently. The waist and seat are so tight I can barely put the pants on, and the thigh is uncomfortably tight as well. The calf/ankle is also clearly tighter. Overall the Rigid Dragon fits more like a 511 than a 541 (I tried on various styles of Levi's jeans in a store, only didn't buy in store because they didn't have the 541 in my size in stock). I can squeeze into the Rigid Dragon 541s but I wouldn't choose to wear them. Very disappointing to see such a stark difference between two different "colors" of what should be the same pants. Levi's shouldn't be labeling both of them as 541 with such a significant difference in fit. I got two pairs of each and the sizing was consistent between each pair of the same color so I don't think it's just a defective pair. If I were comparing two 541s of different material blends I might expect different amounts of shrinkage from washing/drying, but considering that these two I chose were the same blend that shouldn't come into play. Overall I'm happy with The Rich but disappointed that the vastly different fit of Rigid Dragon means I won't be trying other "colors" of 541.
