Long gone are the days of stiff, wrinkled chinos. Modern pants are cut from a different (better) cloth, and Jack Archer's Jetsetter Tech Pants are a prime example. Crafted from premium Rebound fabric sourced from Japan, they're stretchy, wrinkle-free, anti-odor, and stain-resistant, making them great for travel. The fit provides room where it's needed but is slim where it's not, and is enhanced by a diamond-shaped gusset that prevents tightness in the crotch and the curved-waist design that provides a lift to the backside. Built with premium stitching, they also feature a zippered coin pocket and hidden reflective tape that's only revealed when they're cuffed. Now available in two cuts: the original, best-selling Slim Fit and the new Straight Fit, which offer a roomier fit from the knee down.
