The "Gibby Stem Bag" from Swift Industries, the bike bag company based in Seattle U.S.A.

It's the latest stem bag that Swift has released, which is big enough to hold a 1L Nalgene bottle

The bag is oval shaped rather than the traditional stem bags, in order to prevent your knees rubbing on the bag when riding.

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.
