Inspired by a 1947 US Army OD undershirt, the Bronson Tank carries the spirit of vintage military basics into the modern day. Cut from Mister Freeom's signature 100% cotton “Skivvy” tubular knit, it offers a period-correct fit with narrow old-school straps and a single-needle hem. Its name nods to Charles Bronson, who famously wore one onscreen in The Great Escape.
