Hollis St System

ST System

SIMPLE. RUGGED. MINIMALIST.

We designed the ST System for minimalist-minded divers who prioritize streamlining their kit, for the ultimate in traditional simplicity. So if you’re concerned about unnecessary bulk and pieces of equipment failing, the ST eliminates those factors.

The foundation for the ST system starts with our new backplate 2.0 with geometry and material choices tailored to your style of diving. We then added our continuous-weave solo harness. It has no buckles that can fail, and no extra parts that you don’t need. An ultra-streamlined single-tank ST Wing rounds out the system with a perfect balance of horizontal trim and surface floatation. It’s all one simple, ultra-rugged design made for technical dive utility. 

The ST comes pre-assembled from the factory and includes unique components depending on your desired configuration. For warm water and travel destinations we have the ST Travel System, which includes the ST22 wing, Aluminum backplate 2.0, Delrin cam bands and the Backplate backpad 2.0. 

Or those diving in colder waters can choose the standard ST System, which includes the ST35 wing, Stainless Steel Backplate 2.0, Stainless steel cam bands and the Backplate backpad 2.0.
