Best For: Work
The Groundwork Pant doesn't ask permission—it charges straight into the hard crap most pants would quit on.
Our testing crew’s notes read less like reviews and more like a list of double-dog dares: a finish carpenter dropping hundreds of yards of baseboard trim without flinching, an off-road mechanic wrestling a busted driveline on a crumbling mountain switchback, a precision rifle competitor slamming knees-first into gravel-based barricades round after round. Some even called it the honey badger of work pants.
Built with high-stretch, abrasion-resistant durability panels in all the high-wear zones, mesh-lined hip vents that dump heat like a blowtorch, removable knee pads that actually stay put when you need them, and a dialed-in fit that moves with you. Still lightweight and ridiculously comfortable—they punch well above their weight class.
Zero hesitation. Zero compromise. These pants don't just survive the abuse—they spit in its face, refuse to acknowledge limits, and back up every inch of their brutal reputation.
