Public School teams up with the KillSpencer brand to come up with this limited edition backpack and a duffle bag. It has exteriors made out of Italian matte leather and packed with nylon webbing. It has Riri zippers too. Both of the labels have explored the right materials and given much effort during the manufacturing details and process. The two bags are made available starting August 15 with the Weekender at $850 and the Backpack at $575.
