With a large expandable capacity roll-top style, 17" laptop compartment, front zipper and 2 side pockets, this backpack is perfect for office or your next travel adventure. This backpack is also a CHANGE ZERO product, which means that it is developed with a net zero carbon footprint - By using OceanCycle-certified recycled plastic, we reduce 33% carbon emissions from material use (calculated by ecoact(R)). Further, we offset the balance 0.51 kgCO2eq per unit by financing renewal energy projects through Climate Partner, making it a carbon-zero product.
