Most customers will receive their tracking number a few days after ordering, or at least before the backpack arrives. Some customers have received their backpack before the tracking number! We will make sure your backpack leaves the warehouse as soon as possible.These days tracking has become more difficult. We do our best to send you your tracking number as soon as possible. You can always use the Contact Us tab at the top of the page if you are worried. Most probably your backpack is on its way but the tracking not yet. Even with Express shipping, this is rare but there can be delays outside of my control, like at customs, during national holidays and other events. The delivery time of 1-2 weeks is almost always what happens.
