Men's full length Munsingwear union suit, 1890. The union suit is knit of a wool and cotton blend and has long sleeves, a high neck, full open front with twelve white buttons, and a back flap. The suit's knit cuffs are sewn to each sleeve and leg opening.
Minneapolis-based Munsingwear cornered the union suit market in the early 1900s and went on to become the largest underwear company in the world. MN90 producer Marisa Helms tells us that Munsingwear’s rise to under garment dominance all started with the invention of “itchless wool,” a revolution in its time.
When George D. Munsing came to Minnesota in 1886 to produce a new line of woolen union suits, he founded an underwear empire. From long johns to girdles, the Minnesota company urged generations of consumers, "don't say Underwear, say Munsingwear."
