The next pair of jeans in your closet just might just be from Monrovia’s finest, the Railcar Fine Goods Spikes Fit X026. Much requested, they’re RFG’s first ever black jean. They use a 13 oz. Japanese black warp, black weft selvedge denim done up in their slim straight fit. Tonal stitching with a black leather patch means this jean is completely blacked out for a very clean look.

But beauty is only fabric-deep, and although black x black denim isn’t anything new, it’s the construction and vintage machinery behind the jeans that set the X026’s apart. As with everything RFG does, this pair is cut and sewn in-house which, among other things, translates to greater quality control. With sewers who have decades of experience using machines like the vintage Union Special flat-felling machine, single-needle chain stitching machine, and Singer double-needle machines, you can expect some quality stuff.

Available for $198 at Railcar Fine Goods.
