The Hollis CRIB Custom Katana 2 Single Wing is a low-profile backplate and wing system designed for streamlined single-cylinder diving. Built around the Hollis Katana 2 single tank wing, this configuration is intended for divers seeking a compact buoyancy system that supports balanced trim, reduced drag, and efficient in-water movement. It integrates with the CRIB custom harness and backplate platform to provide a modular setup suitable for recreational, travel, and advanced single tank applications.

The Katana 2 single wing uses a donut-style bladder design that allows gas to circulate evenly around the wing, supporting stable horizontal positioning and predictable buoyancy control. Its compact profile is designed to minimize bulk while maintaining sufficient lift for standard single cylinder diving configurations, including use with exposure protection such as wetsuits or lightweight drysuits. The construction emphasizes durability and reliability for frequent use in varied diving environments.

The CRIB custom harness system provides an adjustable and secure fit when mounted to a compatible backplate, allowing for consistent cylinder stability and streamlined hose routing. The modular design supports standard cam band attachment for single tank configurations and accommodates common accessory mounting options. This configuration is designed to reduce clutter while maintaining accessibility and control of essential diving equipment.
