OMS (Ocean Management Systems) — Modular Technical Diving Engineering
OMS has built its reputation on a straightforward principle: technical divers shouldn't have to choose between standardized backplate-and-wing components and a setup that's genuinely tailored to their specific diving. The brand's modular design philosophy lets divers mix and match wings, harnesses, single-tank adapters, and accessories around a consistent core system — building exactly the rig their diving calls for, whether that's a single-cylinder recreational configuration or a fully decked-out technical doubles rig.
At DiveCatalog.com, we carry the current OMS lineup as an authorized dealer: wings, harnesses, hardware, fins, and masks.
The OMS Product Range
Wings
The Performance Mono Wing is OMS's single-tank, donut-style wing, designed for balanced trim and even air distribution around the diver's back — the circular bladder lets air move freely from side to side, reducing trapped gas and improving buoyancy stability. Built with a rugged outer shell and a replaceable inner bladder for long-term durability, with reinforced attachment points and practical dump valve placement. The Deep Ocean Wing 2.0 extends OMS's wing range for divers who need a different lift capacity or configuration profile, while integrating cleanly with the same standard backplate and harness assemblies.
Harnesses
The Comfort Harness III is OMS's premium over-the-shoulder harness, built around genuine all-day comfort — padded shoulder straps, slide-release buckles on both sides, and a sternum strap for a secure, stable fit. The stainless steel waist buckle and adjustable D-ring attachment points add functional flexibility, while a pull-dump path on each shoulder pad, four chest-mounted D-rings, two waist-strap D-rings, and a crotch strap (all corrosion-resistant aluminum) provide the safety-oriented hardware technical diving demands. Installs on any standard backplate, and an OMS comfort pad can be added without removing the harness. Backed by a 12-month limited warranty.
Hardware — Single Tank Adapters and Accessories
The Stainless Steel Single Tank Adapter (STA) is built for divers who regularly switch between single and double tank configurations — mountable on any OMS harness (including DIR and Comfort II configurations), the IQ backpack, and many third-party metal backplates on the market. Stainless steel construction resists corrosion across repeated saltwater exposure, with all mounting hardware included.
Fins
The SlipStream Monoprene fin uses monoprene construction for a balance of flexibility and propulsion efficiency, suited to the kick styles technical divers rely on — including the frog kick favored in cave and overhead environments.
Masks
The Tattoo dive mask rounds out OMS's lineup with accessible, reliable mask construction to complete a full kit alongside the wing and harness systems.
Building an OMS System
OMS's modular approach means components are designed to be mixed across the lineup rather than locking you into a single fixed bundle. A diver running a single tank today can add the Stainless Steel STA to convert to doubles later, without replacing the harness or backplate entirely. The Comfort Harness III installs on any standard backplate, giving you flexibility in backplate material and style while keeping the harness, padding, and D-ring configuration consistent across upgrades.

Frequently Asked Questions — OMS Dive Gear
What is a donut-style wing and why does it matter?
A donut-style wing uses a circular bladder design that allows air to move freely from side to side as you change orientation underwater, reducing trapped gas pockets and helping maintain stable, even trim — a meaningful advantage over wing designs that can develop uneven air distribution.
Can I use the OMS Comfort Harness III with a non-OMS backplate?
Yes — it's designed to install on any standard backplate, giving you flexibility to choose backplate material and brand independently of the harness.
What is a Single Tank Adapter (STA) used for?
An STA lets a harness and backplate system built for doubles (two cylinders) be reconfigured for single-tank use, or vice versa — useful for divers who alternate between recreational single-tank dives and technical doubles configurations without needing two separate complete rigs.
Is OMS gear suitable for recreational divers, or only technical divers?
While OMS's modular backplate-and-wing philosophy is most associated with technical diving, the Performance Mono Wing and Comfort Harness III work equally well for recreational divers who prefer a backplate-and-wing configuration over a traditional jacket-style BCD.
