Irregular slub weave, pant jacket weight mostly linen with some silk. I saw the tab and then lost it there may be some cotton but I know this was mostly linen with a little silk. Has drape especailly considering the weight but really suitable for jackets maybe a duster coat, pants. You will want to line this, I recommend the cotton viscose twill below. The raw linen fibers will need to break in and relax.
