Thanks gents. Interesting point of views about what "raw denim" means and what its real value is. I guess as a marketing term, it's at least an indication that the products using so-called raw denim are qualitatively different from non-raw denim. What that means… Well that's the opportunity to make a statement. And to creatively differentiate. Selvedge does offer an "almost vintage" quality -- and the colorful selvedge stitching is distinctive. The craft of making these denims also seem a vast improvement over the much less expensive alternatives.
Sizing -- interesting to know it's about the thread -- and not applied post weaving. The materials used in the sizing may only be of interest to a data driven individual, but I find it useful and not simply trivia. Starch traditionally was the byproduct of washing the starch from wheat, and vital wheat gluten (a mainly wheat gluten based flour) was a popular product out of Australia -- used for meat-like high protein meat substitutes. For those without gluten sensitivites.
Any information about formaldehyde on the denim used? Doesn't smell like there's much formaldehyde. Does no one really care?
