American workwear has always evolved in the margins — small functional tweaks, innovations, and the kind of ideas that only come from people who actually earn their living in a shirt. Few brands understood this better than Big Yank. Founded by Reliance Manufacturing Co. in the early twentieth century, Big Yank built its reputation on garments that solved real problems long before “utility” became a design trope. Their shirts were ingenious: introducing asymmetrical pockets engineered for cigarette packs and rolling papers, ventilated yokes designed for welders working in the heat, and one-piece “elbow action” cuffs that moved cleanly without catching or tearing.

Nearly a century later, those details are proof that good ideas last. Through the stewardship of Kenji Teramoto and his Tokyo-based label 35 Summers, the Big Yank archive has been preserved with rare fidelity, allowing us to study the originals down to the stitch. 

For our new collaboration, we went back into that archive and rebuilt three of their most compelling designs, each one cut in Japan with the same no-shortcuts approach that defined the original runs. The fabrics are twisted cotton jaspe and salt-and-pepper yarns; the construction is triple-needle, chainstitched, felled, and bartacked where it counts. What you get are three different answers to the same question: what does an honest work shirt look like today?

The 2-Pocket Asymmetrical Work Shirt marks a return to the idea that put Big Yank on the map: one soft-pack cigarette pocket with room to breathe, one oversized utility pocket with a tunneled pen slot. Cut in Japanese jaspe cotton with vintage curved-collar shaping and the brand’s patented barrel cuffs, it’s the clearest expression of Big Yank design DNA.

The Classic Work Shirt brings back Big Yank’s cleanest, most straightforward silhouette: two flap-and-patch pockets, a vintage curve to the collar, and rugged triple-needle construction throughout - a reminder that simplicity, when done right, needs no embellishment.

Born from the mid-century needs of welders and tradesmen working in heat, the 2-Pocket Ventilated Work Shirt is constructed with reinforced triple-needle yokes, embroidered eyelets for airflow, mitered pockets, and gauntlet cuffs — turning an old problem-solving pattern into a warm-weather essential.

Together, these three shirts form our curated survey of Big Yank’s greatest ideas.
