Total processing as seams, buttonholes, etc .: all fine, because there is nothing to complain about. The fabric feels great, soft, but light and strong. The collar is doubled, which is very useful if you want to set it up. The color is not displayed as a lighter shade of brown, but rather a medium to light olive green ("foliage green"), but that's ok, it was known by other reviews.
Unfortunately the resulting XL falls like a well-something short L: arm length and shoulder width LOA clearly running out for an XL. For a good L for people with tummy. Makes me wonder something because others write rather too large than too small.
