The 3005 is the flagship straight fit that defines The Flat Head’s philosophy of authentic denim craftsmanship. In continuous production since the brand’s early days, this timeless model combines vintage American workwear construction with meticulous Japanese manufacturing, resulting in a pair of jeans built to age beautifully for years.

The fabric is an original 14.5oz selvedge denim woven on vintage Toyoda G3 shuttle looms, using U.S. Texas cotton and rope-dyed 24 times in indigo to achieve an exceptionally deep, rich tone. The low-tension weave and dense yarn structure create the bold vertical fades and high-contrast aging that Flat Head denim is famous for. With wear, the denim develops sharp streaking, defined whiskers, and dramatic character unique to each owner.

Construction details reflect true old-school durability. Iron branded buttons, copper rivets, and hidden iron reinforcements age alongside the fabric, darkening and patinating naturally. Raised belt loops, single-needle pocket stitching, and heavy cotton thread throughout emphasize strength while maintaining a clean silhouette. The back yoke is chainstitched using Flat Head’s thick No.8 yarn, producing pronounced puckering and dimensional fades over time.

The regular straight fit features a mid-high rise and minimal taper, creating a streamlined, classic shape without excess bulk. Comfortable, versatile, and easy to wear, it’s a true everyday jean that looks better the longer you break it in.

Finished with a one-wash treatment for immediate wear and minimal shrinkage, the 3005 stands as one of the most iconic Japanese selvedge jeans ever made. Each pair includes a yellow and red “Doshaburi fade” bandana for added style

Fit Notes: The 3005 runs small. In general, we recommend going one size up from your usual. However, as always, we suggest checking the size chart first to ensure the perfect fit. The jeans have been one-washed, so no further shrinkage will occur.
