The Nike Offline Pack ‘Cool Grey’ showcases a unique design inspired by a puffy down jacket. A neutral grey finish permeates the pillowy textile upper, secured with wraparound rope laces and accented with exposed tonal stitching. Reflective detailing lands on webbing eyelets and a pull tab affixed to the heel. A bright green finish is applied to the foam insole, featuring a nubby texture for a massaging feel underfoot. A thick rubber outsole provides durable traction.
