Poly is prob not going to take the dark dye as easily, but that's mostly speculation and inference on my part from reading instructions at various dye company websites.
The Workmans is a cotton duck. I just looked it up and found this review of the material. It says that it takes dye well, and it sounds like a terrific material in general as it is tough but softens over time. I've been thinking of a brown Workmans and now I want one even more (but I like to have front pockets...).

I agree, the poly/cotton blend of the Original and Mocker models (I own two Mockers) seem like they wouldn't take dye very well. Fortunately my favorite UK model is the Survival, which is 100% cotton, so I might just get a couple of those and dye them my colors of choice.
