Williams's explains the sizing:
The ACL Fit as it became known...has a slightly higher rise in the front, a higher rise in the back, a bit of a wider leg and runs straight from the knee to the leg opening. It is a true straight leg jean...In the true spirit of America we even made sure to run the jeans up to a size 40 — so man-sized MF’ers don’t feel left out.Although the photos in the ACL webshop make them look enormous, I've compared the size chart to that of my beloved Epaulet Hoyts and in comparison, the ACL x Telason jeans have a more generous waist, a higher total rise by a little more than 0.5", identical thigh measurements, and about 0.75" larger leg opening. They also have a shorter inseam, between 33 and 34" depending on what size you order.
In the typical ACL fashion, everything is made in America, including the leather patch, supplied by Tanner Goods. Denim is sourced from the seemingly now standard Cone Mills. All the standard accoutrements are there too (five pocket design, button fly, etc.).
ACL Shop (which I suppose is a bit steep for American denim but not much comes close in terms of size aside from a repro pair of LVCs).
