Inspired by the climbing bags and backpacks from the 1980's, Porter have taken those retro influences to create this updated yet visually classic Climbing Back Pack. Although this bag was influenced by real outdoor bags, this design is primarily targeting city use rather than all out outdoor use. Putting focus on detailing with multiple loops that are placed on the center of the backpack as well as leather hoop patches at several points of the backpack. On the technical side of things the outer material is consisted of 4200 nylon and 1000 cordura nylon bringing the backpack to the new millennium. There are purple/navy or purple/red versions available with matte silver lining on the inside.
