Cannot tellCannot tell yet: a major part is unverified

The cloth is 90% cotton and 10% yak wool, dyed by hand with plants in Pennsylvania, and that part reads clean. The buttons are corozo, a nut, by the maker's word. The thread is the gap: American Trench never says what it is, and most shirt thread is polyester. Until the maker names it, the shirt stays off the list.

Not listed, so not linked.

Caveat
Unknown: the sewing thread, the collar and cuff interfacing, the mordant used in the dye bath, the labels and tags, and the packaging. The maker names the buttons as corozo but gives no further detail, and nothing here confirms they are plain nut.
Unverified
Still unverified, and being researched with the maker: buttons; sewing thread; collar and cuff interfacing; dye and mordant; labels and tags.
Made in
USA, from imported cloth
