The Hollis CRIB Custom Katana 2 Dual Wing is a backplate and wing system configured for twin-cylinder diving using the Katana 2 wing platform. Designed for technical diving and extended range applications, this setup supports manifolded double tanks while maintaining a streamlined profile and stable buoyancy control. The system integrates the CRIB custom harness and backplate to provide a modular and adjustable platform suited for demanding diving environments.

The Katana 2 dual wing features a donut-style bladder design that allows gas to move evenly around the wing, promoting consistent trim and balanced lift distribution. Built to handle the increased buoyancy requirements of double cylinder configurations, the wing supports stable horizontal positioning throughout the dive. The construction emphasizes durability with abrasion-resistant materials and an internal bladder designed for reliable gas retention under technical diving conditions.

The CRIB custom harness system attaches to a standard technical diving backplate and is configured for secure twin cylinder mounting. Adjustable webbing allows for precise fit over drysuits or thick exposure protection while maintaining a streamlined and low-drag profile. Hose routing and accessory placement are designed to reduce clutter and support efficient equipment management in overhead environments, cold-water diving, and extended range scenarios.
