The name of the Boss Pant by One Yofukuten refers to their most striking feature: the continuous fly. The namesake overalls featuring this detail were the "Boss of the Road" by The Neustadter Brothers dating back to 1850. The design was patented by David Neustadter in 1877, with the stated goal of making fly construction simpler and stronger. 

The rest of the details on these are straight from the 1910’s. They feature a higher rise with suspender buttons, a buckle back with a WW1-era dead-stock iron buckle from Germany, and the double-knee mentioned above. 100% cotton thread hold them together.

These are sewn up in a 9.5oz double-and-twist denim, rinsed to knock out the shrink. This denim is true to the era for workwear in style and weight, and will wear in beautifully.

As with all Ooe Yofukuten jeans, they are sewn one pair at a time by husband and wife team Ryo and Hiro Yofukuten at their workshop in Ichinomiya, Japan. Ryo does all the patterns and cutting, while Hiro sews every pair. Their workshop is in a textile factory building from the 1890’s, filled with restored vintage sewing machines (which are lovingly maintained their close friend Mr. Matsuoka, nationally recognized by Japan for his sewing machine repair skills).

These have been given a hot rinse already. Our recommendation is to take a size 2” up from your usual jeans; or your true waist size (often 2” larger than the tag size for your denim). For example, if you wear a size 34 in most denim, take the 36”. If you want a roomier fit, size up accordingly.
