Hollis CRIB Custom Dual Tank 45 Dual Bladder Wing Package

The Hollis CRIB Custom Dual Tank 45 Wing Package is a backplate and wing system configured for double-cylinder diving applications requiring increased buoyancy capacity and stable trim control. Built around the Hollis DT 45 donut-style wing, this setup is designed for technical diving, extended range recreational diving, and overhead environments where twin tank configurations are used. The system combines the CRIB custom harness and backplate platform with a high-lift wing engineered for balanced gas distribution and streamlined underwater performance.

The DT 45 wing provides approximately 45 lb (20 kg) of lift and utilizes a donut-shaped bladder design that allows gas to move evenly around the wing for improved horizontal trim and buoyancy stability. Constructed with a rugged 1000D Cordura outer shell and a heavy-duty internal urethane bladder, the wing is designed for durability in demanding diving conditions. The dual tank configuration supports consistent buoyancy control when managing increased gas volume, stage bottles, and technical equipment.

The CRIB custom harness system integrates with a stainless steel or aluminum backplate to provide a stable and adjustable platform for twin cylinder mounting. The design supports standard manifolded double tanks with compatible hardware and allows for streamlined hose routing to reduce entanglement and drag. Multiple adjustment points on the harness allow configuration over exposure suits, supporting both cold-water and technical diving environments.
