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 features a half-moon design with ample space for daily essentials and weekend getaways. The base gusset features a lugged bottom to stand on its own.
