The military shade, made correctly.

Buzz Rickson's BR78711 — a reproduction of the standard-issue WWII US military undershirt, built to the original GI specification. Heavyweight cotton tube-knit: ribbed set-in collar, single chest pocket on the left breast, lockstitched seaming throughout. Made in Japan by Toyo Enterprise. In olive, the shade that sits closest to the original GI palette — between green and khaki.

Olive. Works against everything. Reaches for nothing extra.
