Freediving Wetsuits: Our Top Tips to Choose The Right One

In the alluring world of freediving, enthusiasts plunge into the depths with a single breath, embracing the ocean’s embrace and exploring its silent mysteries. As the sport gains traction globally, equipping oneself with the right gear becomes paramount.

At the forefront of essential equipment is the freediving wetsuit. Not just any ordinary aquatic attire, these wetsuits play a pivotal role in a diver’s safety, comfort, and overall underwater experience.

Why Wear a Wetsuit for Freediving?

  • Thermal Protection Against Hypothermia: The ocean’s depths are colder than they appear. As divers go deeper, water temperatures drop, increasing the risk of hypothermia. A wetsuit acts as an insulator, trapping a thin layer of water between the suit and the skin. This water heats up due to body temperature, providing a warm barrier against the cold external environment.
  • Enhanced Buoyancy and Protection: Besides cold, divers also contend with potentially harmful marine life, jagged rocks, and coral. A wetsuit offers a protective layer against minor abrasions, stings, or cuts. Additionally, the wetsuit’s neoprene material aids in buoyancy, helping divers maintain their desired depth without excessive effort.
  • Improved Hydrodynamics: Anyone who’s tried swimming in regular clothing knows the drag clothes create. Wetsuits, with their streamlined design, reduce this drag, enabling smoother, more efficient movement through the water.

Types of Wetsuits: An Overview

  • Full suits vs. Shorties:
    • Full suits cover the entire body, from the wrists and ankles up to the neck. They are ideal for colder waters, offering maximum thermal protection.
    • Shorties, on the other hand, usually end around the elbows and knees. They’re best suited for tropical or warmer waters where full coverage isn’t necessary.
  • Thickness Variations: The thickness of a wetsuit determines its insulating capacity. For colder waters, a thicker wetsuit (e.g., 5mm or even 7mm) is recommended. In contrast, for tropical dives, a 2mm or 3mm suit suffices. It’s crucial to match the wetsuit’s thickness to the dive location’s average temperature.
  • Open-cell vs. Closed-cell Wetsuits:
    • Open-cell wetsuits have a soft, raw neoprene interior. They provide a snug fit and are warmer due to the direct contact with the skin. However, they can be trickier to put on and are more fragile.
    • Closed-cell wetsuits have a lining inside, typically nylon. They are more durable and easier to wear but might not offer the same level of insulation as open-cell suits.

Freediving Wetsuit: Features to Consider

Material

The material of the wetsuit is of utmost importance for a freediver. Neoprene is the go-to choice for most wetsuits. It offers insulation, buoyancy, and flexibility. When diving, freedom of movement is crucial; hence, opting for a wetsuit that offers a balance between thickness (for warmth) and flexibility is key.

Seams

The way a wetsuit is stitched together can greatly affect its performance.

  • Stitched seams are common and tend to be more affordable. However, they can allow a small amount of water to seep through the holes made by the needle.
  • Glued seams, often found in higher-end wetsuits, are bonded together without perforating the material, offering better water-tightness and warmth.

Zippers vs. No-Zippers

Traditional wetsuits come with back zippers for ease of entry. However, in freediving, zipper-less designs are gaining popularity. Not only do they offer a more snug fit, but they also eliminate potential entry points for cold water. While they might be a bit more challenging to put on, the hydrodynamic benefits and warmth are considered worth the effort by many freedivers.

Integrated Hoods

The head is one of the body’s primary heat loss areas. An integrated hood in a wetsuit ensures that this critical area is insulated. Besides keeping the diver warmer, it offers a streamlined profile, reducing drag during the dive.

Selecting the Right Wetsuit for Freediving

Depth Considerations: The deeper a diver goes, the colder the water generally becomes. Additionally, pressure at depth compresses the wetsuit, reducing its insulation capabilities. Divers aiming for greater depths might consider slightly thicker wetsuits or those designed specifically for deep dives.

Water Temperatures: The first thing to consider when choosing a wetsuit is the water temperature of your usual dive sites. As mentioned earlier, thicker wetsuits (5mm to 7mm) are ideal for colder waters, while 2mm or 3mm suits are suitable for tropical climates.

Personal Comfort and Fit: A wetsuit should feel like a second skin. Too loose, and it will allow cold water to flush in; too tight, and it can restrict movement and breathing. It’s always recommended to try on multiple sizes and styles before settling. Additionally, keep in mind areas prone to chafing, especially around the neck, armpits, and seams.

Caring for Your Freediving Wetsuit

A well-maintained wetsuit can serve a diver for years. Proper care not only ensures durability but also guarantees optimal performance during each dive.

  • Rinsing: After every dive, thoroughly rinse your wetsuit with fresh water. This helps to remove salt, sand, and other debris that can degrade the neoprene over time.
  • Drying: Always dry your wetsuit in the shade, as direct sunlight can cause the neoprene to lose its flexibility and become brittle. Hang the wetsuit inside out on a wide hanger to prevent stretching or deformities.
  • Storing: Store your wetsuit in a cool, dry place. Avoid folding it, as this can create permanent creases. Instead, hang it up or lay it flat.
  • Ensuring Longevity:
    • Minor Repairs: Small nicks or tears can be easily repaired using specialized wetsuit adhesive. Address these minor damages promptly to prevent them from expanding.
    • Avoid Direct Sunlight: Prolonged exposure to UV rays can degrade the neoprene. Always dry and store your wetsuit out of direct sunlight.
    • Stay Clear of Sharp Objects: Be wary of fins, corals, or any sharp objects while wearing your wetsuit to prevent unintentional tears.

Final Thoughts

Wetsuits play an indispensable role in the freediving realm. They offer protection, enhance performance, and most importantly, keep divers warm in the water’s depths. By emphasizing the nuances of fit, design, and material, divers can make an informed choice tailored to their needs.

As with all diving gear, a wetsuit is an investment – in safety, comfort, and countless underwater adventures. By choosing wisely and caring for it diligently, you’re ensuring many memorable dives ahead.

Frequently Asked Questions

Can I use a surfing wetsuit for freediving?

While both surfing and freediving wetsuits are designed to insulate, there are differences in design and function. Freediving wetsuits typically offer a closer fit, are more flexible to ensure unhindered movement, and may have features like integrated hoods or zipper-less designs for better hydrodynamics.

It’s possible to use a surfing wetsuit for freediving, but for optimal performance, a specialized freediving wetsuit is recommended.

How often should I replace my freediving wetsuit?

The lifespan of a wetsuit depends on its usage frequency, the conditions in which it’s used, and how well it’s cared for. With regular use and proper care, a wetsuit can last several years. Signs that it’s time for a replacement include loss of flexibility, persistent bad odor, or noticeable thinning of the neoprene.

What’s the difference between men’s and women’s freediving wetsuits?

Men’s and women’s wetsuits are designed to fit the typical anatomical differences between male and female bodies. Women’s wetsuits might have narrower shoulders, wider hips, and specific bust designs. It’s essential to choose a wetsuit that fits your body type closely, regardless of gender labeling, to ensure optimal performance and comfort.
