Business casual shirts rarely do more than look crisp and wrinkle‑free. Mack Weldon’s new Silver Jersey Button Up aims to change that by combining soft knit fabrics with anti‑odor technology. The shirt is cut from a blend of Supima cotton — prized for its extra‑long fibers — Lycra for stretch and silver‑infused threads that use antimicrobial ions to fight odors. The result feels more like a high‑end T‑shirt than a stiff button‑down, but it still features a structured collar, button placket and adjustable cuffs.

The Silver Jersey’s knit construction offers better breathability than a traditional poplin, and the 5 percent Lycra content helps the shirt maintain its shape throughout the day. Mack Weldon finishes the hem with a slight curve so it looks neat tucked or untucked. The fabric is pre‑shrunk and machine‑washable for easy care, and the shirt comes in a range of muted colours like navy, black and heather grey. At around $128, it slots in between budget basics and designer dress shirts.

The brand has already built a following with its performance underwear and sweats, so expanding into office‑ready shirting is a logical next step. For other wardrobe staples, consult our guide to the best men’s dress shirts.
