Porter's signature Tanker series is reborn using 100% plant-based nylon, the first of its kind in the world. Still inspired by MA-1 military flight jacket uniforms, it features a custom-developed 3-layer fabric, with a resilient twill exterior and ultra-soft, padded lining in emergency orange. The main compartment accommodates B4-size documents and a 15-inch laptop, while a zippered pocket on the back provides extra storage.
