Filson denim brings our trusted legacy of workmanship to an everyday staple. In a world overrun with inferior goods, our Rail-Splitter Jeans offer a refreshing difference: exceptionally-high quality denim, cut with room to move freely on the job or hard at play.

We searched the globe for the right material–denim fabric that would live up to our legacy of tough clothing that withstands the tests of time and hard use. North America, Europe of the Japanese islands–wherever the best could be found, that’s where we landed. Sewn in the USA by experienced craftsmen and women to our exacting standards, our jeans represent the values on which we’ve stood for more than a century – offering our customers long-term value by manufacturing durable goods built to last.

The right-hand-twill denim is tightly-woven with 100% cotton yarns for natural durability and comfort. Preshrunk, they will remain true-to-size with the recommended laundering and care. Because we know that it’s frustrating to have pockets blow out while there’s still plenty of life left in a pair of jeans, we put a twist on the classic 5-pocket styling, adding double-layer reinforcing to the bottoms of the rear-patch pockets and the heavy-twill front-pocket bags.

These durable jeans are cut with straight legs to minimize excess fabric, but with enough room to move, squat and climb without binding. The leg holes will fit over all but the bulkiest boots, and the rise is slightly higher than typical straight-leg jeans to provide more ease of motion. The heavy-duty zippered fly and metal wreath-button waist closure ensure longevity. The waistband boasts sturdy bar-tacked belt loops and a washable-leather Filson logo patch.
