Built to last with quality craftsmanship, durability and functionality running through every single stitch. The only accessory in our Alpha Industries collaboration, the Alpha backpack is engineered for attitude on-the-go with a blend of Smooth leather, Kiev leather and Nylon. Functional from zip to strap, it features added pockets, rugged material and a removable Alpha Industries pull tab — a feature taken directly from their famous MA-1 flight jacket. Pull tab reads: REMOVE BEFORE FLIGHT. Hardwearing and famously tough, our Smooth leather can be polished to shine or scuffed-up. It's up to you. Clean with a damp cloth and care with Dr. Martens Shoe Polish. Kiev is a hardwearing, rigid leather with a smooth surface and slight sheen. Clean it with a camp cloth and care with Dr. Martens Wonder Balsam. Nylon is a lightweight woven fabric with exceptional strength, toughness and elasticity. Gunmetal hardware.
