Same US Navy herringbone twill as the Khaki, VAT-dyed and reproduced from 1940s shipboard fatigue cloth. The Black version reads differently in context: less overtly workwear, more useful in inner-city or evening settings without losing the texture and structure that HBT gives.
VAT-dyeing matters here. Black HBT is prone to fading grey, and most reproductions go that way within a season. Wearmasters' version holds. Cut with a tapered leg over a regular thigh, finished with chain-stitched seams and herringbone pocket linings. Made in Japan.
Wears well with the Lot.872 slip-ons in white, the Solovair Gibson, or RATS knitwear when you want workwear structure without the workwear reference.
