OMS SideStream 27 Double Bladder Sidemount System – Redundant Safety for Tech Divers
The OMS SideStream 27 twin-bubble sidemount system is the ultimate choice for demanding cave dives, wreck explorations and ambitious technical diving.
This highly advanced sidemount BCD (Buoyancy Control Device) combines an extremely streamlined profile with the highest level of safety in the water. Thanks to its integrated, redundant double bladder, the system offers maximum protection against sudden loss of buoyancy in confined and critical diving environments.

- Material : Extremely robust, abrasion-resistant nylon fabric without failure-prone external zippers
- Weight management : Integrated spine weight pocket for up to 15 kg of lead
- Ergonomics : Flexible split-backplate design for stepless adjustment to any torso length
- Accessories : Includes robust buttplate with offset stainless steel D-rings for optimal trim
The key features in detail
1. Maximum reliability through redundant double bladder
The heart of the OMS SideStream 27 is its dual bladder system. The main bladder is controlled conventionally via the smooth-running corrugated hose inflator. Should damage occur in an emergency, the second, fully functional safety bladder is immediately available. This is inflated orally via a separate supply hose. This ensures that technical divers retain full control over their buoyancy, even in extreme situations.
2. Perfect trim & integrated back weight system
The integrated spine weight pocket allows for clever weight distribution of up to 15 kg directly at the body's center of gravity. The weight can be positioned in three separate zones to effortlessly maintain perfect horizontal trim. The top quick-release valve is ergonomically accessible over the shoulder, allowing for easy deflation even in tight spaces without changing position.
3. Adjustable ergonomics and robust buttplate
The split backplate design adapts to your needs: The 5 cm (2 inch) wide webbing can be adjusted to the exact length of your torso. The integrated buttplate, with its strategically placed D-rings, ensures that sidemount cylinders (whether aluminum or steel) sit perfectly against your body throughout the dive. A variable bungee system reliably secures the cylinder valves under your armpits.
💡 Why buy the OMS SideStream 27?
For those who refuse to compromise on technical diving, the OMS SideStream 27 offers the perfect symbiosis of minimalism and redundancy. It minimizes water resistance, protects equipment from damage in confined spaces, and, thanks to its double bladder design, provides crucial safety backup for deep and overhead dives.
