Modular weight system: The Stealth 2.0 easily handles the ideal placement of weight, from a 1kg block to over 12kg, without fuss.
High lift capacity: 19kg of lift - perfect for technical diving with multiple cylinders, yet incredibly slender, even when fully inflated.
Tough and Durable: Nylon 440 dTEX inner shell enclosed in a Cordura 1100 dTEX outer shell with enhanced abrasion and puncture resistance.
Reinforced upper wing: Provides protection in tight restrictions inside caves and wrecks, eliminating snagging hazards.

XDeep STEALTH 2.0 TEC Sidemount System Features

Critical Positioning

Dump Valve: Unlike many sidemount wings with one-side valves, the Stealth 2.0 TEC places its dump valve in the centre, letting you vent excess gas with either hand while maintaining perfect trim—even with multiple cylinders.

Inflator Feed: The Stealth TEC also lets you adjust the inflator feed position from left to right, giving you greater flexibility.

Quick-adjust XDeep Stealth 2.0 Harness

The Stealth 2.0 TEC wing attaches securely to the harness, keeping you stable during deep dives and decompression stops. Its adjustable harness - with independently adjustable shoulder, waist, and crotch straps plus repositionable D-rings - makes achieving the perfect multi-cylinder fit quick and easy.

The Stealth 2.0 harness uses three types of webbing for optimal performance: rigid waist webbing for precise cylinder placement, soft shoulder straps for comfort and mobility, and a supportive, gentle crotch strap that protects your drysuit.

Weight Placement System

The TEC system offers effortless weight management, handling weights ranging from a 1 kg block to over 12kg. Divers can rely on consistent performance and comfort, no matter the dive.

Its weight placement system allows precise positioning relative to your centre of gravity. The central pocket can be adjusted across a wide range, making it easy to achieve perfect balance and trim—even when diving with 5 or 6 cylinders—using the same principles as V or tail weights on a twinset.

Designed for both security and flexibility, the Stealth 2.0 weight system keeps weights firmly in place while remaining simple to adjust. In technical diving, where multiple gas mixes and thick drysuits increase the importance of correct weighting, this system ensures divers maintain optimal balance and confidence underwater.

XDeep Stealth 2.0 TEC vs REC: Which Sidemount System is Best?

Choosing between the XDeep Stealth 2.0 TEC and REC sidemount systems can determine how far your diving progresses. While both share the same innovative platform, they are designed for very different purposes.

The REC is perfect for straightforward recreational dives, offering simplicity and comfort. However, the TEC version goes much further—providing greater lift capacity, improved durability, and true scalability for more demanding environments. READ MORE

Product FAQs

Is the Stealth 2.0 Tec better than the Rec?

Even if you're a recreational diver, if you plan on going deeper, staying longer, exploring within wrecks, caverns or caves in the future, the Stealth 2.0 Tec is future-proof.

It's lift capacity, and harness design are the primary differences from the "recreational" Rec version. The Stealth 2.0 REC provides only 13kg (28.6 lbs) of lift and features a harness with quick-release (QR) buckles similar to jacket-style BCDs. It's designed for recreational dives typically involving no more than two cylinders.

The Stealth 2.0 TEC is built for heavy-duty technical diving, offering 19kg (41.8 lbs) of lift to support multiple stage cylinders. Its harness is a DIR-style (Doing It Right) single-piece webbing without break points, providing maximum stability and durability. The TEC wing also features a reinforced upper section to protect against abrasion in overhead environments like caves or wrecks.

Can I use the Stealth 2.0 Tec for my recreational diving?

Of course you can. Being able to manage up to eight cylinders doesn't mean you have to max out. The Stealth 2.0 TEC is very versatile and can be used for recreational diving just as effectively as for deep technical dives. Its design allows it to remain incredibly streamlined even when fully inflated. Many divers actually prefer the TEC for recreational use because it is "future-proof."

What weight system does the Stealth 2.0 Tec use?

Similar to the REC, the Stealth 2.0 TEC utilises the same central modular weight system. A system that is one of the most acclaimed features of the Stealth 2.0 series, as it places the weight along the diver’s spine, allowing for perfect trim and balance.

The weight pockets come in various sizes (Small, Medium, Large, and Wide) and can hold up to 22kg (48.5 lbs) of lead, depending on size.

You can swap between a TEC wing and a REC wing while keeping your harness and weight configuration identical, making the system outstandingly modular. With the Stealth weight system, you'll achieve a "flat" horizontal trim, regardless of whether you are diving in a wetsuit or a drysuit.

Does the Stealth 2.0 Tec have a custom-colour option?

Oh yes, although it takes a bit more time for the manufacturer to produce and ship. But it'll be well worth the wait! Check out the Stealth 2.0 Tec in Colour.

Is there a Redundant Bladder version of the Stealth 2.0 Tec?

Like the rest of the Stealth series, there certainly is. You can have it in standard black or even order the Stealth 2.0 Tec RB Wing System in colour.
