Similar to the baseline ST, the ST Elite brings together our most popular single tank components into a single system. However, instead of the solo harness, we added our luxurious and adjustable Elite 2 harness, yielding a result similar to what you’d expect from a full-featured BCD.So if you’re coming from the recreational world of single tank diving using a traditional BCD, this gives you that same harness style, but on a backplate for added stability. The ST Elite System also gives you a ton of options to customize depending on your diving style, in case it changes over time.And those diving in colder waters can choose the standard ST Elite, which includes a go anywhere ST35 wing, Stainless backplate 2.0, stainless cam bands and a backplate backpad 2.0.
