Pool

Pool

The pool is one of the core training environments for anyone practicing apnea and freediving. Its controlled setting, free from the variables of open water, makes it possible to work systematically on specific technical aspects: finning control, improved hydrodynamics, and body coordination without heavy equipment. For these sessions, there are products designed specifically for pool use, different from open-water gear in size, function, and construction features.

In this category, Deep Blue brings together equipment intended for pool training for freedivers: short training fins, technical swim briefs, and silicone swim caps. A focused, functional selection featuring products from Salvimar and C4, intended for those who include pool work in their apnea training program.

Product Types

Short Training Fins

Short fins for pool use are a specific training tool, not equipment for open-water use. The Salvimar Training Fin is a compact fin with a light, responsive blade, designed for pool swimming and sessions focused on improving finning technique. Its shorter length compared to apnea or freediving fins makes it easy to handle in the pool, where the propulsion typically required in open water is not necessary. The foot pocket is anatomically shaped for a comfortable fit, with availability in four sizes: 38/39, 40/41, 42/43, and 44/45.

Technical Swim Briefs

The Salvimar Fluyd Slip is a men’s swim brief designed for pool training sessions in a freediving context. Available in light blue in sizes M, L, and XL. This is a technical swimwear garment suitable both when paired with short fins and for freestyle pool swimming sessions.

Silicone Swim Caps

The C4 Cuffia Silicone is a pool swim cap made from soft hypoallergenic silicone by C4. It adapts to the head thanks to the flexibility of the silicone material, providing comfort during extended training sessions. The finish features a carbon-effect look, characteristic of the C4 aesthetic. It is a practical accessory to complete the pool kit of anyone who trains regularly in the pool.

How to Choose Products for Pool Training

Choosing pool equipment depends on the goal of the training session and the type of exercises planned.

For those working on finning technique, short fins are specific training tools. The reduced blade length requires a higher finning cadence compared to long freediving fins, allowing you to isolate and strengthen the leg muscles and refine movement coordination. Choosing the correct size is essential: an inaccurate fit reduces the effectiveness of the fin and can cause irritation during prolonged sessions. 

The silicone swim cap, compared to other materials, is soft and elastic, easily adapts to any head shape, reduces the risk of skin irritation in sensitive users, and lasts longer in chlorinated water than latex.

Brands, Materials, and Technical Features

Salvimar: The short Salvimar Training Fin fins feature a light, responsive blade. Blade responsiveness refers to its ability to return mechanical energy to the fin stroke, while the lightweight material reduces fatigue during repeated training sessions. The foot pocket is anatomically shaped for a stable fit during movement in the water.

The Salvimar Fluyd Slip swim brief is a brief-style model, a type widely used in competitive swimming and aquatic training for its low hydrodynamic drag and the full freedom of movement it provides for the legs and hips. 

C4: The Cuffia Silicone is made from hypoallergenic silicone. Silicone is a biocompatible material, free from the latex proteins responsible for allergic reactions, and withstands the effects of chlorine in pool water better than other elastomers. The surface of the cap features a carbon-effect finish, consistent with the aesthetic identity of the C4 brand.

Conclusion

Deep Blue’s Pool category brings together technical equipment for pool training in the context of apnea and freediving. The products available, from Salvimar and C4, cover the essential needs of a pool session: the short Training Fin fins for work on finning technique, the Fluyd Slip technical swim brief for freedom of movement in the water, and the C4 hypoallergenic silicone swim cap for protection and compatibility with the mask when submerged. A functional selection for those who regularly combine pool training with open-water activity as an integral part of their freediving development.
