A buoyancy compensator (BCD) doesn't become good simply by adding up technical features. It becomes useful when it stops occupying the diver's mind. The Mares Dragon SLS falls into the category of wrap-around jackets and makes a specific promise: to serve a practice oriented towards leisure and training. This article is not a substitute for a trial, but it allows you to know exactly what the model offers and what problems it doesn't solve. [1]
The question isn't so much whether this BCD is performant in absolute terms, but rather whether it suits your tank, your thermal protection, your weighting system, your accessories, and your progress. As a wrap-around jacket, this model prioritizes a volume distributed around the torso. Therefore, you need to check underwater that this envelope doesn't restrict breathing and that the surface position remains comfortable. [2] [3]

Average Price (estimated 2026). The amount of €389 is an arithmetic average of the available new price range. This is neither a real-time price nor a commercial promise.
The stated buoyancy is 19.3 kg, which is equivalent to 42.5 lbs. This value should not be considered in isolation. It represents the overall negative buoyancy of the complete configuration, including the tank, gas, wetsuit, weights, and accessories. An insufficient value can reduce comfort at the surface. Conversely, an excessive value does not automatically make a dive safer. [4]This is a solid, entry-level to mid-range BCD. The buoyancy is generous for its category. It lacks trim pockets - something to consider for divers who want to fine-tune their position. Metal D-rings are present. Based on this assessment, the Mares Dragon SLS receives a G1 score of 3.8/5. Trim and purge control must be tested under actual diving conditions, not just in shallow water. [1]
The model features a jettisonable weight system with a stated capacity of 5.9 kg. It includes 0 trim pockets. This configuration can help adjust buoyancy, but it doesn't replace proper weighting procedures. Weights should always be easily accessible and appropriate for the environment. [3]
The G2 score of 3.3/5 reflects the capacity and logic of this weight system. Before purchasing, verify the actual function of the pockets with your own weights and your usual wetsuit.
The Mares Dragon SLS includes 2 storage pockets and 4 metal D-rings. The specifications describe these attachments as being made of stainless steel. This information is important when carrying items such as a pony bottle, a reel, a light or a camera housing. [1]
The G3 score of 3.2/5 does not evaluate the absolute volume of a pocket. It expresses the suitability between the available attachment points and accessories commonly used for recreational diving and training.
The G4 score of 3.5/5 reflects the potential for adjustability in this design. A test dive should confirm that the straps don't pull, the waistband doesn't ride up, and the controls remain accessible when the BCD is inflated.
The stated weight is 3.2 kg, and the construction is advertised as 420D Cordura. The D-rings are made of metal. These details indicate expected durability, resistance to wear and tear, and ease of transport, but they alone cannot determine the longevity of a specific unit. [1]
The G5 score of 3.5/5 reflects this assessment of the materials used. The actual condition of a used BCD, including any servicing, inflators, and purge valves, should be checked independently of the year it was manufactured or the brand's reputation.
The configuration is advertised for recreational use and training, suitable for warm and temperate waters. The specifications indicate no declared dual-tank compatibility and no declared sidemount compatibility. Therefore, in this configuration, its actual uses are limited to single-tank setups. [1]The G6 score of 2.5/5 indicates its ability to adapt to changes in diving practices, but it doesn't suggest that one model is suitable for everyone. A shift towards more technical diving may require a different system rather than simply adding accessories.
The first check concerns buoyancy. With a declared buoyancy of 19.3 kg, the Mares Dragon SLS needs to be tested with your actual equipment configuration. A thicker wetsuit, a steel tank, saltwater, a housing, or a light can significantly change the required buoyancy. The right decision starts with a buoyancy check at the end of the dive, not based on a general rule. [4]
The second check concerns comfort. This model features standard straps with QR buckles. Wear it with your usual thermal protection and then, while underwater, check your breathing, access to purge valves, the direct system, and the position of the tank. A poorly fitted BCD adds mental strain that a diver should be dedicating to their surroundings and dive buddy. [2]The third check is regarding its use. As a wrap-around jacket, this model prioritizes a volume distributed around the torso. It's important to verify underwater that this design doesn't restrict breathing and that the surface position remains comfortable. The identified qualities – generous buoyancy (42.5 lbs), metal D-rings, an accessible price, durable 420D Cordura material – should be weighed against its limitations: no trim pockets, limited weight capacity (5.9 kg), and a jacket design which can result in less precise trimming. The average indicative price of €389 in 2026 is a point of comparison, but never a safety criterion.

The stated buoyancy, price, and rating do not replace a trial dive, a weight check, or appropriate training. Any modification to the tank, wetsuit, weights, or accessories requires re-checking the entire configuration. For wrap-around jackets, the correct approach is to understand the equipment before entrusting it with responsibilities that it cannot handle alone. [2] [3] [4]
