I was looking at some of the longcoats on offering at the fest, and one is thornweave.

The wiki entry doesn't list any sort of durability/season metric for the cloth, just that it's woven from a specific plant, and that it holds 'matte' colors well (which kind of confuses me since one of the longcoats is viridian thornweave, and viridian is typically very bright)

Should I consider the material equivalent to cotton, for clothing purposes? For example: If you had a silk coat, you wouldn't wear it in winter, or the rain. The opposite is true for canvas.

Based on the description and the kind of items it's showed up in, I always imagined it like a fancy plant-based wool with an affinity for darker applications (presumably in reference to Dergati). Could be wrong tho'.
