What makes denim unique is that the material becomes better with age. With extended wear, it eventually fades and becomes softer, taking on more character while the fabric's overall comfort is improved. For the more adventurous, you can skip ahead several months and just apply bleach for a radical new look. And as Instagram user @arab_lincoln demonstrates, the denim used on the Levi's x Air Jordan 4 will react to bleach precisely the same way that a pair of Levi's 501s will. Trace amounts of indigo are left behind on the white denim twill, resulting in a one-of-a-kind pair that's sure to turn heads.
