Introduction
Freediving is a mesmerizing dance with the ocean, where divers challenge their limits by diving deep into the blue, relying solely on a single breath. As enchanting as it sounds, the sport demands the right gear, especially when it comes to wetsuits. This guide delves into the intricacies of wetsuit thickness, temperature considerations, and the types tailored for freediving.
Understanding Wetsuit Thickness and Temperature
When selecting a wetsuit for freediving, it’s essential to consider the water temperature you’ll be diving in. Wetsuit thickness is measured in millimeters (mm) and typically ranges from 0.5mm to 7mm. The thicker the wetsuit, the warmer it will keep you, but it may also restrict movement slightly.
Here’s a general guideline for choosing wetsuit thickness based on water temperature:
- Water Temperature 85°F (29°C) and above:
- Wetsuit Thickness: 0.5mm – 2mm
- Type: Rashguard or thin wetsuit top
- Water Temperature 73°F – 84°F (23°C – 29°C):
- Wetsuit Thickness: 2mm – 3mm
- Type: Spring suit or full suit
- Water Temperature 66°F – 72°F (19°C – 22°C):
- Wetsuit Thickness: 3mm – 4mm
- Type: Full suit
- Water Temperature 50°F – 65°F (10°C – 18°C):
- Wetsuit Thickness: 4mm – 5mm
- Type: Full suit with gloves and booties
- Water Temperature 43°F – 49°F (6°C – 9°C):
- Wetsuit Thickness: 5mm – 6mm
- Type: Full suit with hood, gloves, and booties
- Water Temperature 42°F (5°C) and below:
- Wetsuit Thickness: 6mm – 7mm
- Type: Full suit with integrated hood, gloves, and booties
Remember, these are general guidelines. Individual tolerance to cold may vary, and other factors like dive duration and activity level can influence the ideal wetsuit thickness. Always prioritize comfort and safety when choosing your wetsuit.
Types of Freediving Wetsuits
Freediving requires wetsuits that offer flexibility, warmth, and a snug fit. Here’s a closer look at the different types:
1. Open-cell Wetsuits
Open-cell wetsuits are favored by many freedivers due to their superior warmth and snug fit. The inner layer sticks to the skin, creating a tight seal, minimizing water movement inside the suit.
- Advantages:
- Provides excellent thermal insulation.
- Offers a snug fit, reducing drag underwater.
- Disadvantages:
- Can be challenging to put on without a lubricant.
- More fragile compared to lined wetsuits.
2. Lined Wetsuits (Outside Lining)
Lined wetsuits come with an external lining, usually made of nylon. This lining protects the raw neoprene, making the wetsuit more resistant to wear and tear.
- Advantages:
- Durable and resistant to scratches or cuts.
- Easier to put on compared to open-cell wetsuits.
- Disadvantages:
- Might not offer the same level of warmth as open-cell wetsuits.
3. Smoothskin / Superskin Wetsuits
Smoothskin wetsuits have a smooth, unlined outer surface. These wetsuits are incredibly flexible and reduce drag, making them perfect for competitive freediving.
- Advantages:
- High flexibility ensures unrestricted movement.
- Reduced drag improves diving performance.
- Disadvantages:
- More susceptible to damage from sharp objects.
- Can be more expensive than other wetsuit types.
4. Types of Neoprene
Neoprene is the primary material used in wetsuits. There are different types:
- Standard Neoprene: Common type used in wetsuits. Offers good flexibility and insulation.
- Yamamoto Neoprene: Known for its superior flexibility and warmth. Lighter than standard neoprene.
- Sheico Neoprene: Offers a balance between flexibility and durability.
- Limestone Neoprene: Made from limestone, this type is more eco-friendly and provides excellent warmth and flexibility.
Conclusion
Choosing the right wetsuit for freediving is crucial. It affects performance, safety, and comfort underwater. By understanding the different types and materials, you can make an informed decision that best suits your freediving needs.
