I realized that my two favorite pairs of thrifted corduroy pants (different manufacturers, one O'Connell's and the other Orvis) were both made with Brisbane-Moss cloth and when I looked them up lo and behold they had data sheets on their website to look through!

Here is the datasheet for their ultra heavy weight corduroy which is so beefy it out weighs most japanese selvedge denim! The warp to weft ratio is absolutely bonkers. https://www.brisbanemoss.co.uk/wp-content/uploads/2025/05/GS20-2024.pdf
