Backpack comes with extra black bag for additional storage and wristlet that fits inside the removable front pouch. The backpack also comes with an adjustable strap at the chest. Why we made this- We designed this 2-in-1 bag to work overtime. The removable front pouch has an adjustable strap so we can wear it on its own or we can attach it to the backpack for a quick-access secure pocket. Double duty never looked so good.
