Hollis ST System

The Hollis ST System combines the brand’s most popular single tank components into one streamlined, factory-preassembled setup. Built around the minimalist Solo Harness, this system includes the ST35 wing, Stainless Steel Backplate 2.0, and Backplate Backpad 2.0 for a clean, durable, and travel-friendly configuration.

The ST35 wing features a 360° tapered profile that improves lift distribution and promotes better horizontal trim underwater while maintaining excellent surface flotation. With 35 lbs. of lift, it is ideal for both cold-water diving with heavier steel cylinders and lightweight travel setups. Integrated tank slots and cradle eliminate the need for a single tank adapter, reducing extra weight and accessories.

Constructed with a rugged 1680D Cordura outer shell and durable 420D inner bladder, the ST35 is built for long-lasting performance. Additional features include an easy-access lower OPV for quick gas venting and a crushproof K-style inflator hose for reliable inflation and positioning underwater.
