The ultra-versatile chino just got a major upgrade in comfort too. It starts with the two-way stretch, moisture-wicking cotton/nylon/spandex fabric. Add to that the gusset in the crotch, the articulated knees, and the fixed waist with its interior elastic flex-comfort waistband, and you've got serious, unrestricted mobility. When walking in low-light conditions, you can roll up the hem to expose the reflective binding strip to enhance your visibility.
