At first glance, they look like the classic weathered flat front chinos your Dad wore home from the war, and basically lived in for the rest of his civilian life. But under the second belt loop on each side of the fly hides a special comfort secret: an elastic band that allows up to 3" of extra ease. Think how good that's going to feel when you're crouching, stretching, climbing a ladder or trying to get comfortable in a coach seat. Hidden Crouch Gusset® adds even more ease in action.
