That's what I recall, as well. Some questionable quality control issues surrounding the stitching around the toe box, and people complaining about the CXL leather (which is typical among other brands, too). I love my natty cxl trench boots.
I don't need something that heavy. I've got the oka standards, the japan union blue and the graphite chinos. Now that I think about it, the union blues are 12oz and they are fairly lightweight, so the indigo canvas would be even lighter. Ehhh...I'll probably pass. It would be nice as a chino, but I'm flush with navy chinos, lol.
