100% lambswool collar, button down cardigan with pockets. Fibers are very soft. Brooks 346 is from Brooks Brother and it’s really great quality. Ribbed edges. I mended a small hole near pocket, pictured, barely noticeable. This piece is in great shape, no pilling or other flaws. Pictured on a s/m, 5’8 frame. Pit to pit 19 1/2”, length 25 1/2”. Fits like a medium.
