Don't take the name literally. The Topo Design's Dirt Pants, part of its Dirt collection, are part of an initiative to clean up the production process. Made from sustainably-sourced organic cotton, the Dirt Pants feature a straight-leg design with drawstring cinch, classic detailing, and side seam and back patch pockets. A garment wash makes for a soft feel and color, giving these pants a lived-in fit that's perfect from the first wear. Available in Dark Khaki and Black.
