The 226 Long sleeve henly made by Merz B Schwanen, a great henly on denim, with olive Orslow shirts, or on navy shorts or workers. This is one of those pieces you need when you are into a casual "made in Japan (or similar high quality products)" pieces.
It's one of those shirts you will keep for years, but i warn you here; Don't buy it to small, because it shrinks! This is a cotton like in the past, no chemicals were used to produce so it's like denim that's unsanforized, size one size up.
Made in Germany, on old looms, knitting slow and tubular, even the box it comes in and the tags are locally made.
100% cotton, made in Germany.
