When it comes to selecting a wetsuit, flexibility is one of the most critical factors that can significantly impact your performance, comfort, and overall experience in the water. Whether you’re a triathlete, an open-water swimmer, or a surfing enthusiast, the flexibility of your wetsuit will affect everything from your range of motion to your ability to swim efficiently.
In this blog, we will explore why flexibility is so essential in wetsuits and guide you through understanding how much flex your wetsuit needs, how to choose the right wetsuit for flexibility, and how to maximize your performance while staying comfortable in the water.
Triathlon Westuits: Too tight? Will it stretch?
Understanding Wetsuit Flexibility
A wetsuit’s flexibility refers to its ability to stretch and move with your body, especially around key areas like the shoulders, arms, and legs. The flexibility of a wetsuit is determined by the thickness and type of neoprene used, as well as how the panels are constructed and stitched together.
Flexibility is particularly crucial for triathletes and swimmers because it directly affects your ability to perform swimming strokes efficiently. Wetsuits with optimal flexibility allow for greater freedom of movement, which reduces drag and improves overall speed and efficiency in the water. For example, the lining of Sumarpo Victory wetsuits uses super-elastic SQ-Flex fabric, a world-leading super-elastic fabric, combined with Yamamoto #45 neoprene at the shoulders, which can provide 680% elongation at the shoulders of top athletes.
Factors That Determine Wetsuit Flexibility
-
Neoprene Thickness: The thickness of the neoprene greatly influences the flexibility of a wetsuit. Generally, the thinner the neoprene, the more flexible the wetsuit will be. However, thinner neoprene also provides less insulation, so you’ll need to balance flexibility with warmth depending on the water temperature.
For example, a 1-2mm wetsuit is highly flexible and ideal for warm water conditions, while a 4-5mm wetsuit provides more warmth but less flexibility, making it better suited for colder environments.
-
Type of Neoprene: Not all neoprene is created equal. High-end wetsuits, such as those from Sumarpo, use premium neoprene like Japanese Yamamoto neoprene, which is renowned for its superior flexibility and durability. This type of neoprene offers greater stretch and comfort, allowing for an enhanced range of motion compared to standard neoprene materials.
-
Panel Design and Seam Placement: The way the neoprene panels are stitched together also affects the wetsuit's flexibility. Wetsuits with fewer seams or strategically placed seams allow for better movement in key areas like the shoulders and legs. Flatlock stitching or seamless designs provide greater stretch and reduce irritation, making the suit more comfortable during long swims.
-
Zipper Location: The placement of zippers can also impact flexibility. Back-zip wetsuits are easier to put on but may restrict some movement in the shoulders. Chest-zip and zip-free wetsuits offer better flexibility in the upper body but may be more challenging to get in and out of.
Determining the Right Level of Flexibility
The amount of flexibility you need in your wetsuit will depend on the type of water activity you’re engaging in. Triathletes and swimmers typically require more flexibility in the arms and shoulders to allow for efficient swimming strokes, whereas surfers may prioritize flexibility in the lower body for better maneuverability on the board.
In general, if your wetsuit is too stiff, it can tire your muscles faster and hinder your performance. On the other hand, a wetsuit with the right amount of flexibility will allow you to swim, paddle, or dive comfortably without feeling restricted or fatigued.
How to Choose the Right Wetsuit for Flexibility
1. Consider Your Sport and Activity Level
Different water sports require varying levels of flexibility. Triathletes and open-water swimmers need wetsuits that allow for a wide range of motion in the arms, shoulders, and chest to enable effective swimming strokes. For these athletes, a wetsuit with a thinner neoprene layer around the shoulders and arms (such as 1-2mm) is ideal, as it reduces resistance and allows for more effortless arm movement.
In contrast, surfers might focus on wetsuits that offer flexibility in the legs and torso to facilitate their movements on the board. Divers, on the other hand, may prioritize warmth and insulation over flexibility since they spend more time in colder water.
2. Choose the Right Wetsuit Thickness
As mentioned earlier, the thickness of the neoprene plays a significant role in determining a wetsuit’s flexibility. Here’s a quick guide to choosing the right neoprene thickness based on water temperature:
- Warm Water (20°C/68°F and above): Opt for a thin wetsuit (1-2mm) that offers maximum flexibility.
- Mild Water (15°C-20°C / 59°F-68°F): A wetsuit in the 2-3mm range provides a balance between warmth and flexibility.
- Cold Water (10°C-15°C / 50°F-59°F): For colder water, a thicker wetsuit (4-5mm) is necessary for warmth but may limit flexibility.
- Very Cold Water (Below 10°C/50°F): Choose a 5-6mm wetsuit for optimal insulation, though flexibility will be reduced.
Remember that thinner neoprene will allow for more movement but provide less insulation, so it’s essential to choose a wetsuit that matches the water conditions you’ll be swimming in.
3. Look for Premium Neoprene Materials
High-quality neoprene, such as Japanese Yamamoto neoprene, offers superior flexibility and comfort. This type of neoprene is lightweight, highly stretchable, and provides excellent buoyancy and thermal insulation, making it a popular choice for triathletes and open-water swimmers.
Sumarpo’s wetsuits, for example, are made from premium neoprene that combines flexibility with durability, ensuring that athletes can move freely in the water while staying warm.
4. Check for Multi-Panel Construction and Seamless Design
When choosing a wetsuit, look for a design that incorporates multi-panel construction and seamless technology. This ensures that the wetsuit conforms to your body’s natural shape and movement while minimizing restrictions.
Wetsuits that use fewer seams or flatlock stitching in key areas (like the arms and legs) offer greater flexibility. Seams should be strategically placed to avoid chafing and reduce resistance in the water.
5. Test the Fit
No matter how flexible the wetsuit material is, the overall fit will determine how comfortable and functional the suit is. A well-fitting wetsuit should feel snug but not overly tight. You should be able to move your arms and legs freely without feeling constricted, and the suit should not bunch up or create gaps.
When trying on a wetsuit, simulate swimming movements to check the flexibility in the shoulders and chest. If the wetsuit pulls on your shoulders or restricts your arm movement, it may be too small or not flexible enough for your needs.
Maximizing Performance with a Flexible Wetsuit
Once you’ve chosen the right wetsuit for flexibility, there are a few additional tips to keep in mind to ensure you get the most out of your gear.
1. Proper Care for Maximum Flexibility
Taking care of your wetsuit is essential for maintaining its flexibility over time. Always rinse your wetsuit with fresh water after each use, especially if you’ve been swimming in saltwater. Avoid exposing your wetsuit to direct sunlight for extended periods, as UV rays can degrade the neoprene and reduce its flexibility.
Hang your wetsuit on a wide hanger to prevent stretching, and store it in a cool, dry place when not in use.
2. Use Lubricants for Easy Wear
Some swimmers and triathletes use wetsuit-specific lubricants around the neck, arms, and legs to reduce friction and make the suit easier to put on and take off. Lubricants can also help reduce chafing in areas where the suit may rub against the skin.
3. Train in Your Wetsuit
Before a race or competition, it’s essential to train in your wetsuit to get used to how it feels in the water. Practicing in your wetsuit will help you identify any areas of discomfort or restriction so that you can adjust your technique or fit before race day.
Conclusion: Flexibility is Key to a Great Wetsuit
In the world of wetsuits, flexibility is more than just a comfort feature—it’s a performance booster. Whether you’re a seasoned triathlete, an open-water swimmer, or a casual surfer, having the right amount of flexibility in your wetsuit can make all the difference.
By understanding how much flex your wetsuit needs and choosing a wetsuit that balances flexibility with warmth, you can enhance your performance and stay comfortable in the water. Sumarpo’s wetsuits, made from premium neoprene materials, offer the perfect combination of flexibility, warmth, and durability, ensuring you’re ready for any water adventure.
