The Hollis CRIB Custom Single Tank 22 Wing Package is a modular backplate and wing system configured for streamlined single-cylinder diving. Built around the Hollis ST 22 donut wing, this setup delivers balanced lift, reduced drag, and stable trim for recreational, technical, and advanced open water divers using a single tank. The system emphasizes durability, adjustability, and compatibility with standard backplate components, making it suitable for both warm-water travel and local diving conditions.

The ST 22 wing provides approximately 22 lb (10 kg) of lift in a compact, donut-style bladder that promotes even gas distribution and predictable buoyancy control. Constructed with a rugged 1000D Cordura outer shell and a heavy-duty internal urethane bladder, the wing is designed to resist abrasion and withstand repeated use in demanding environments. Integrated with the CRIB custom harness and backplate configuration, the package offers a clean hose routing profile, secure cylinder attachment, and a stable platform for efficient propulsion and trim.

This single tank wing package supports standard cam band attachment, optional single tank adapter use, and compatibility with common backplate accessories. The minimalist harness layout reduces clutter while maintaining multiple adjustment points for fit and comfort over exposure suits. The result is a streamlined buoyancy system that prioritizes control, durability, and modularity for divers who prefer a backplate and wing configuration over traditional jacket BCDs.
