The "Zeitgeist Pack" from Swift Industries, the bike bag company based in Seattle U.S.A.

The Zeitgeist bag is a modernized version of a classic British style touring saddle bag.

The main material utilizes “SI600X,” a high-performance recycled polyester fabric developed exclusively for Swift, designed to meet the functional demands of bicycle bags used in the rough environments.

The outer fabric utilizes 600 denier recycled polyester, thicker than the previously used ECOPAK (400 denier), achieving superior abrasion resistance.

The inner side features a waterproof film laminated with diamond-shaped reinforcement fibers, ensuring high waterproofing and durability.

Its matte finish, reminiscent of classic Cordura nylon, is another key feature.

A simple flap top design enables the users to stuff tons camping goods and other loads.

If you own a shoulder strap, you could use the Zeitgeist as a shoulder bag as well.

We recommend using a bag supporter when you are carrying heavy items.
