The IJ1 is a roomy, straight fit worker-style pant inspired by a pair of 1870s denim from Antonio’s collection. The JP03 is made of an 11oz Japanese grey-indigo pinstripe denim, and were first made in collaboration with denim collector Brit Eaton, aka Indiana Jeans. It features a buckle back, brace buttons, back flap pockets, and arcuate stitching around the front pocket.
