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

This is the small version of one of their best selling bike bag, "Zeitgeist". There were dozens of requests from the Zeitgeist users to make a smaller version, and here it is now.

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.

Riders with narrower bar widths and shallower head tube tolerances, or really, anyone looking for a bomber mid-capacity pack, now have a new option for stowing gear up front and off the saddle!

The Catalyst Pack is perfect for gravel adventures, road touring, bikepacking, the daily grind, and even XC-MTB!
