Freediving Wetsuits

Wetsuits for freediving and freediving one-piece and jacket+pants, in neoprene from 1.5 to 7mm, lined or smooth/open-cell, for men and women, with integrated hood and flatlock or glued & blind-stitched seams.

Introduction

The Freediving Wetsuits category at Deep Blue brings together freediving wetsuits designed for freediving, in both one-piece and jacket plus pants versions, designed for both men and women. These garments are made from neoprene with thicknesses generally ranging from 1.5 mm to 7 mm, available in smooth/lined, smooth/open cell and double-lined configurations, according to the thermal protection and mobility requirements of the activity in the water. The wetsuits in this section cover a wide range of uses, from thinner versions for warm water and pool training to thicker wetsuits designed to provide greater thermal protection in cold water.

The selection includes long-established and specialized brands in the freediving sector, with models ranging from entry-level options to technical wetsuits intended for sport practice and training in the pool or in the sea.

Product types

Within the category there are mainly two types of wetsuits: one-piece and two-piece.

One-piece wetsuits are the most common configuration for freediving. They are a single garment that covers the body from the ankles to the neck, generally with an integrated hood, designed to minimize water entry through seams and zippers. The continuous neoprene fabric over the entire body helps reduce heat loss compared to a wetsuit divided into two separate garments.

Jacket plus pants wetsuits (two-piece) consist of a jacket, often with a hood, and separate pants or farmer john. This configuration allows greater flexibility in fit and easier management of the overlap between the two garments at the waist, with a double-layer effect that can increase thermal protection in that area of the body.

Specific models for women and models for men are also available, as well as sleeveless or long-sleeve shorty wetsuits designed for particular climate conditions or for use during pool training where arm mobility is a priority.

How to choose a Freediving Wetsuit

Choosing a freediving wetsuit is based mainly on three factors: the neoprene thickness, the type (one-piece or two-piece) and the internal and external finish of the material.

Thickness determines the level of thermal protection. A 1.5-2 mm wetsuit is suitable for relatively warm water conditions and pool use, while greater thicknesses, up to 5-7 mm, are recommended for colder water or longer dives, where body heat loss becomes a relevant factor for the duration of the session in the water.

The type affects the practical handling of the wetsuit. A one-piece reduces the number of joins between garments and tends to limit water entry, generally making it warmer at the same thickness. A two-piece configuration makes donning and doffing easier and allows the overlap between jacket and pants to be adjusted according to personal needs.

The neoprene finish is another element to consider. Smooth/open cell wetsuits have an open-cell neoprene interior that, by adhering directly to the skin, reduces empty spaces where water can circulate, helping to maintain a more stable microclimate compared to the outside. This configuration generally requires the use of a lubricant (water and mild soap or specific products) to make donning easier, precisely because of the material’s adherence to the skin. Smooth/lined and double-lined wetsuits, featuring a textile lining on one or both surfaces, are easier to put on and generally more resistant to wear, at the cost of slightly lower flexibility compared to open-cell versions.

Size must be assessed carefully, as a wetsuit that is too loose allows water to circulate freely inside, reducing the effectiveness of thermal insulation, while a wetsuit that is too tight can limit rib cage expansion during breathing and restrict movement during descent and ascent.

Materials and technical features

The main material used to make freediving wetsuits is neoprene, a cellular synthetic elastomer that contains tiny air bubbles inside, which are responsible for its insulating capacity. Among the neoprenes used in the freediving sector, Yamamoto is one of the most recognized materials, appreciated for its high elasticity and light weight compared to other neoprenes of the same thickness, features that translate into greater freedom of movement during swimming and buoyancy control in the water.

Surface finishes affect the performance and practical handling of the garment. The smooth/open cell finish, when in contact with the skin, reduces the formation of a film of water between the body and the wetsuit. The smooth/lined finish reduces external friction with the water while swimming and makes donning easier thanks to the internal lining.The double-lined configuration has a textile lining on both sides of the neoprene, offering greater resistance to tearing and abrasion, at the expense of lower elasticity compared to open-cell versions.

The seams used in wetsuit construction may be flat-lock, which join the neoprene panels by placing them side by side and stitching them to obtain a flat seam, or made with glued and blind-stitched techniques, which limit needle penetration through the thickness of the neoprene, reducing potential water entry points through the seam itself.

Practical use

The freediving wetsuits in this category are used mainly in two contexts: open-water freediving (sea, lake) and pool training.

In open-water freediving, the wetsuit provides thermal insulation during sessions that may involve repeated descents and ascents, surface intervals between breath-holds and potentially extended overall exposure times. In this context, the choice of thickness depends on the water temperature and the expected duration of the session.

For pool training, where thermal conditions are generally more stable and controlled, thinner wetsuits are often used, between 0.5 mm and 1.5 mm, or sleeveless variants that leave greater freedom of movement for the arms while swimming, while reducing the drag generated by the fabric during the stroke.

In addition to thermal protection, a freediving wetsuit provides mechanical protection for the skin against abrasions caused by contact with rocks, reefs or substrates and helps limit direct skin exposure to solar radiation during surface sessions.

The garment is part of the overall freediving equipment together with other accessories such as masks, fins, weights and safety systems, helping determine the freediver’s overall trim in the water through the volume and inherent buoyancy of the neoprene.

Available brands

In the Deep Blue Freediving Wetsuits category, models are available from C4, Mares, Cressi, Salvimar, Beuchat, Pathos and Cetma.

C4 offers the widest range within the category, with several one-piece models for both men and women, available in multiple thicknesses and variants, including sleeveless and long-sleeve shorty wetsuit versions.

Mares, Cressi, Salvimar are represented with one-piece wetsuits dedicated to both the men’s line and the women’s line, in different thickness ranges.

Beuchat and Pathos are represented with a men’s one-piece model.

Cetma offers a freediving wetsuit with a "carbo skin" finish, available in numerous variants.

Conclusion

The Freediving Wetsuits category at Deep Blue offers a selection of freediving wetsuits in one-piece and two-piece configurations, made from neoprene with thicknesses ranging from 0.5 mm to 7 mm, in smooth/lined, smooth/open cell and double-lined finishes, with men’s and women’s models offered by brands such as C4, Mares, Cressi, Salvimar, Beuchat, Pathos and Cetma. Choosing the most suitable model depends on the conditions of use, water temperature and personal preferences in terms of flexibility, thermal protection and ease of donning.
