Elastic Freediving Belts

Belts for Freediving

The weight belt is one of the essential pieces of equipment for freediving and freediving. Its purpose is to hold the weights needed to offset the positive buoyancy generated by a neoprene wetsuit, allowing the freediver to achieve proper trim both on the surface and during the descent. A well-chosen and correctly adjusted belt helps provide stable trim, reducing the effort required to start the descent and maintaining proper body position during static, dynamic, or depth freediving.

This category includes elastic belts of various types, closure systems, and materials, as well as accessories and spare parts for their adjustment and maintenance. The selection includes products suitable both for pool freediving and for training or diving in the ocean, with solutions designed for different needs in terms of elasticity, safety, and comfort.

Product types

Within the category, different types of weight belts are available, each featuring a specific closure system.

Marseillaise belts are the most popular type among freedivers. These are elastic belts equipped with a special buckle, built with a roller (or cylinder) that allows the belt to slide freely through it, and with a locking pin that remains in a forced-open position. This configuration allows the belt to be released quickly and intentionally, while at the same time preventing accidental opening during use. The Marseillaise buckle is available in versions with a stainless steel body or in plastic/nylon, and the belt itself may be fabric-covered or left as exposed rubber, with different color options.

Elastic belts with traditional buckles use simpler closure systems, made of plastic or stainless steel, generally more affordable and suitable for pool use or for beginners.

Also available are kits and accessories for modular closure systems, such as double-belt systems with spacers, designed to distribute the weight load across multiple points on the body and improve weight distribution.

The category is completed by accessories and spare parts: belt keepers to secure the excess belt after cutting, replacement elastic rubber for replacing the strap, spacers for double-belt systems, and lumbar pads to pair with the belt to reduce direct pressure on the lower back area.

How to choose Freediving Belts

The choice of weight belt mainly depends on the type of activity, the preferred closure system, and the freediver’s waist circumference.

For ocean freediving, especially in conditions where it must be possible to quickly release the ballast in an emergency, the Marseillaise belt is the most widely used solution thanks to the quick-release mechanism integrated into the buckle. For pool training, where safety requirements are different, elastic belts with a traditional plastic or steel buckle may also be sufficient.

Another factor to consider is the elasticity of the belt, which varies according to the material and strap thickness. A belt that is too stiff can be uncomfortable and restrict chest movement during breathing, while a belt that is too elastic may not keep the weights stable during descent and ascent. The choice of elasticity therefore also depends on the thickness of the wetsuit being used and the amount of weight to be carried.

It is also important to assess the length of the belt in relation to your waist circumference while wearing the wetsuit: Marseillaise belts are sold in a standard length and must be cut to size by the user, leaving a few centimeters of excess beyond the buckle, with at least two holes, so it can be gripped and pulled to activate the quick release without the excess section being wrapped around the belt itself.

For those using double-belt systems, choosing the right spacers and fastening accessories makes it possible to distribute the ballast weight between the main belt and the crotch strap, reducing pressure concentrated on a single band of the body.

Materials and technical features

Freediving weight belts are mainly made from three elastic materials: rubber, high-density neoprene, and silicone. The choice of material, together with the thickness and Shore hardness of the strap, determines the belt’s elastic response and therefore its behavior during use.

Rubber belts generally offer good resistance to the load of the weights and maintain their elastic properties over time, even with frequent use in salt water. Neoprene belts have a softer surface in contact with the wetsuit, while silicone belts tend to offer greater resistance to UV rays and wear over time.

As for closure systems, stainless steel buckles provide better corrosion resistance than plastic buckles, a particularly relevant feature for those who use the belt regularly in seawater. Plastic or nylon buckles, on the other hand, are lighter and are often chosen for primarily pool-based use or training where prolonged contact with salt water is limited.

The roller mechanism of the Marseillaise buckle, regardless of the material it is made from, reduces friction between the buckle and the belt as it slides, making both length adjustment and quick-release activation easier.

Accessories such as the belt keeper allow the excess strap to be secured after cutting it to size, keeping the belt tidy and preventing the excess from interfering with the release mechanism. Lumbar pads, used together with the belt, are made from material that distributes the weight load over a larger surface area than the elastic strap alone.

Practical use

The weight belt is worn over the wetsuit at pelvis level and loaded with the number of weights required to achieve the desired trim according to wetsuit thickness, operating depth, and the freediver’s body type. Correct belt positioning, kept stable by the elasticity of the material, prevents the weights from shifting along the torso during duck dives, descents, and ascents.

In ocean activities, the ability to quickly release the belt using the Marseillaise buckle is a safety feature when needed, as it allows the diver to immediately get rid of the weight load. For this reason, many Marseillaise belts are used both in sport freediving and during open-water training.

After each use in salt water, it is recommended to rinse the belt with fresh water to remove salt and residue, dry it completely before storing it, and avoid prolonged exposure to direct sunlight in order to preserve the material’s elasticity over time. It is also useful to periodically inspect the belt for any signs of wear, cracking, or deformation of the strap and buckle mechanism, replacing damaged components with the available spare parts.

Available brands

The category includes belts and accessories from brands specialized in the freediving sector, including Sigal Sub, Pathos, C4, Cressi, Beuchat, Mares, Rob Allen, Salvimar, Picasso, Best Divers, Omer, Pikotech, and Deep Blue.
