Determine the size of the backpack by the amount of stuff you need to carry; the Eastpak Provider makes this happen due to the adjustable side buckles. In addition, the 33 litre size backpack has two main compartments, including an organizer, a padded 15’’ laptop sleeve and a front pocket. For extra comfort, the shoulder straps are double padded, the bottom is reinforced, and the Provider is equipped with rubber handles.
