BIGMIKE was founded in Illinois, USA in 1890. Since its founding, it has focused on the manufacture of workwear, and its development capabilities have been recognized, and it is said that it was involved in the production of military specifications. In particular, when it began manufacturing flannel work shirts, BIGMIKE, with its excellent development capabilities, developed durable and high-quality flannel shirts. BIGMIKE's flannel shirts overturned the image of agriculture and forestry, and are said to be a brand loved by a wide variety of workers, including construction workers and mechanics, and have become one of the three BIG in the workwear industry, along with BIGYANK, BIGMAC, and BIGMIKE. They used to be available as second-hand clothes, but now they have almost disappeared and are very difficult to obtain even in the vintage market. In Japan, we propose products that fit the trend while inheriting the DNA of good old American workwear.
