When you need something compact yet spacious for a day trip or hike, this 18L backpack is your new go-to. The lightweight design has plenty of room with multiple pockets and compartments to organize your essentials. Other features include a breathable mesh panel that is ergonomically designed to support your back and to create excellent airflow to keep you dry. The ergonomically-designed shoulder straps offers better support and carrying comfort. Stay hydrated on the move with two large water bottle pockets and a compartment for a water bladder or laptop. Made with 10 plastic bottles, which were used in the lining, mesh, webbing, and labels. The outer shell fabric and certain buckles were made with Econyl nylon, which comes from waste such as discarded fishing nets, fabric scraps, carpets and industrial plastic.
