Porter is stepping it up in the weather-resistance department with their new Paramount Packer bag range that utilizes a tough Cordura exterior coupled with a GORE Fabric waterproof membrane. The two materials are sandwiched together to create a complex armor against the elements and GORE-SEAM taping adds another line of defense. The bags come in three styles, each with olive exteriors and all the functionality you'd expect in a Porter bag.
