The Kinesis system uses a unique TwinBuckle attachment system to connect components to the belt or piggy-back smaller pouches to larger cases. A metal "figure 8" (also called a "slider or butterfly") functions like a shirt button, attaching the pouches to a belt or piggy-back to other pouches. A pair of these buckles or figure 8s is sewn into every Kinesis belt pouch or case. This two-point system provides more stability than a single "behind the pouch" attachment method.
Additionally, pouches from other manufacturers can be attached to a Kinesis belt or piggy-back to the outside of a long lens case with a B590 accessory strap.
Note: This system works with all Kinesis belts, including those pouches sold with our prior to 2000 which used a cam buckle attachment system.
