The Ames workshirt is made from a unique handwoven fabric dyed with naturally derived dyes. The warp yarns have been dyed with sappenwood, while the weft yarns are left undyed. The 2x1 weave gives it enough heft, drape, and breathability to be worn year round. Inspired by classic Big Mac work shirts, this Ames shirt is slightly oversized to be worn layered or by itself.
