XDEEP Stealth Review for Sidemount Divers
A sidemount system can look deceptively simple: a harness, a wing and a few attachment points. In the water, however, small setup choices determine whether your cylinders sit cleanly alongside you or hang low, whether you can reach your valves, and whether buoyancy feels controlled at the end of a dive. This XDEEP Stealth review looks at the system from that practical perspective, with particular attention to fit, trim and the configurability that makes it popular with both progressing recreational divers and technical sidemount divers.
The Stealth is not a plug-and-play BCD in the conventional sense. That is a strength for divers prepared to set it up properly, but it also means the best result comes from treating the harness, buoyancy unit, weight system and cylinder rigging as one complete configuration rather than separate purchases.
What the XDEEP Stealth Is Designed to Do
The XDEEP Stealth is a sidemount platform built around a minimalist harness and a low-profile buoyancy system. Rather than placing a large bladder around the diver’s torso, its buoyancy sits behind the body. This allows the chest and waist area to remain comparatively clear, while leaving room to position cylinders close to the sides.
That layout suits sidemount’s central objective: a balanced, streamlined diver with accessible valves and independently managed cylinders. It can work very well for warm-water recreational diving with aluminium cylinders, but it has enough adjustment range and component choice to appeal to divers planning steel cylinders, overhead training or more equipment-intensive dives.
The important distinction is that Stealth configurations are purpose-led. A diver making reef dives in a thin wetsuit has different buoyancy and weighting needs from someone diving twin steel sidemount cylinders in a drysuit. Choosing the appropriate Stealth wing and arranging the system around the actual cylinders, exposure suit and dive plan is more useful than simply selecting the largest-capacity option.
Harness Design and In-Water Fit
The harness is one of the strongest aspects of the Stealth concept. It uses a continuous-webbing style of layout, with substantial adjustment available at the shoulders, waist and crotch strap. Once correctly fitted, it stays close to the body and avoids the bulk of a jacket-style BCD.
For divers who have struggled with a conventional BCD riding up, this close fit can be a real improvement. The harness should carry the system from the hips and keep the waist strap secure without restricting breathing. It also provides a stable foundation for the D-rings, lower cylinder attachment points and optional accessories.
That said, adjustment takes patience. Webbing that is too loose allows the system to shift and makes cylinder trim inconsistent. Webbing that is too tight can make donning awkward and may limit comfortable reach. The crotch strap, in particular, needs enough tension to prevent the harness moving upwards without pulling uncomfortably when standing or climbing a ladder.
A properly fitted Stealth should feel almost unremarkable underwater. The cylinders should be supported by the harness and bungee system rather than relying on the wing to hold them in place. If a diver feels that the wing is doing all the work, the cylinder attachment and bungee length usually need further attention.
Cylinder Positioning Is the Real Test
The first few dives in any sidemount system are an adjustment period. With the Stealth, cylinder trim depends on several linked details: where the neck bungees hold the valves, the position of the upper and lower clips, the tension and length of the bungees, and the location of any weight.
Aluminium cylinders become increasingly buoyant at the base as gas is used, so many warm-water divers need to adjust the lower attachment or use a suitable trim solution. Steel cylinders behave differently and may demand a different setup entirely. There is no single correct setting that transfers between every cylinder type.
This is where a custom approach is valuable. A system that is excellent for local quarry or sea diving in a drysuit may not be ideal for a Singapore holiday configuration using 80 cu ft aluminium cylinders and a lightweight wetsuit. Recording your working settings once you have found them makes future assembly much quicker.
Buoyancy, Trim and Wing Choices
The rear-mounted buoyancy cell is the feature that gives the Stealth its distinctive profile. With air distributed behind the diver rather than around the ribs, it is easier to keep the front of the body uncluttered. This is useful when managing long hoses, clips, reels or stage equipment, and it can also provide a more horizontal swimming position when the system is tuned well.
XDEEP offers Stealth options intended for different levels of buoyancy demand. The right choice should be based on the total amount of buoyancy required, not an assumption that more lift is always safer. An oversized wing may be bulkier than necessary and can hold more air than a lightly equipped diver can manage neatly. Conversely, insufficient lift can leave little margin for a drysuit, heavy cylinders or added equipment.
The system’s trim can be very good, but it is not automatic. Sidemount divers sometimes expect a new wing to cure feet-down trim or trailing cylinders. In practice, trim is a whole-system outcome. Fin buoyancy, exposure protection, cylinder type, tank bands, lower clip placement and weight location all matter.
For this reason, initial pool sessions or shallow familiar dives are worthwhile. Start with a conservative configuration, make one adjustment at a time and assess how the cylinders sit at the beginning, middle and end of the dive. Trying to correct every issue at once makes it difficult to identify the cause.
Weight Integration and Configuration Options
The Stealth weight system is designed to keep ballast close to the body and around the diver’s centre of balance. This is preferable to placing all weight on a standard belt, particularly when the amount of ballast needed changes between wet and dry exposure protection.
Its modularity is a major advantage. Weight can be distributed to support horizontal trim rather than simply carried wherever there is space. A diver with floaty feet may need ballast positioned differently from someone whose drysuit and fins already pull their lower body down. The aim is neutral, relaxed trim, not forcing a horizontal position through uncomfortable posture.
There is a trade-off. More configuration options mean more decisions, and it is possible to overcomplicate a system with unnecessary pouches, hardware and accessories. Begin with the essentials: an appropriate wing, correctly fitted harness, sensible weight placement, cylinder bungees and reliable lower attachments. Add accessories only when they solve a defined problem.
Divers considering cameras, reels, lights or additional stages should also think about D-ring placement before cutting webbing to its final length. The Stealth can accommodate a capable technical setup, but tidy routing and accessible attachment points are more valuable than adding hardware for every possible future use.
Comfort, Travel and Everyday Use
For travel, the Stealth has clear appeal. The harness packs flat and avoids the rigid structure of many conventional BCDs. Depending on the chosen components, it can make a relatively compact sidemount package for divers travelling with their own regulators and essentials.
The practical downside is that it demands familiarity. A conventional rental BCD is generally quicker for a dive centre to issue and easier for an occasional diver to use without preparation. The Stealth rewards ownership, repeat use and a willingness to understand one’s setup. It is best suited to divers who want consistent personal equipment rather than a universal compromise.
Donning can also feel unfamiliar at first, especially when wearing a drysuit or thick wetsuit. With the harness adjusted correctly, it becomes routine, but it is worth practising on land and keeping the webbing layout simple. Clean, repeatable assembly reduces the chance of finding a twisted strap or misplaced clip at the water’s edge.
Who Should Choose the XDEEP Stealth?
The Stealth is a compelling option for a diver committed to learning sidemount properly. It suits recreational divers who value a streamlined, personal configuration, as well as technical divers who need a platform that can develop with their diving. Its strengths are fit range, low-profile buoyancy and the ability to tune weighting and cylinder position instead of accepting a fixed layout.
It may be less suitable for someone who wants the quickest possible out-of-the-box experience or only dives occasionally on holiday using whatever cylinders are available. Those divers can still enjoy sidemount, but should expect time for setup and ideally seek hands-on guidance from an experienced instructor or equipment specialist.
Before ordering, be clear about the cylinders you will use most, your exposure suit, the ballast you typically require and whether your dives are recreational, technical or heading towards overhead environments. Deep Dive Supplies can help turn those details into a configuration rather than a collection of parts. The best Stealth setup is the one that disappears from your attention underwater, leaving you free to monitor your gas, enjoy the dive and keep your trim relaxed.
