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 rescue orange.

The Envelope Bag comes equipped with a variety of interior pockets. The main compartment is sized to accommodate a long wallet, with organized pockets for everyday use and travel.
