Vibrant color brightens this work-to-workout backpack with a stretchy toggle cord securing its fold-down top that offers more room than you'd think. The sturdy fabric is coated on the front bottom for a little bit of water-resistance and extra strength, while mesh padding in the straps and back make the sporty bag extra comfy for extended wear. Style Name: Nike Radiate Training Backpack. Style Number: 5901241. Available in stores.
