Sailfish Ultimate IPS Plus 4 Wetsuit

A wetsuit is a key piece of equipment for any triathlete or open water swimmer. It not only provides warmth in cold water, but also buoyancy, stability and – not least – the ability to swim faster and more efficiently. At Transition Zone, we stock wetsuits from two of the strongest brands on the market: Sailfish and ZONE3. Whether you are new to the sport or an experienced swimmer, there is a wetsuit to suit your needs, your body and your level of ambition.

But what is the difference between a cheap and an expensive wetsuit? Why can one wetsuit cost twice as much as another, even though they are similar at first glance? The short answer is: technology, material and freedom of movement. A wetsuit is not just neoprene. The right combination of thicknesses, flexibility, fit and surface treatment has a huge impact on how you float, breathe and move in the water. And these are precisely the factors that improve with price.

The biggest difference between a top model and a more affordable wetsuit is the choice of materials and construction. Top models often use extremely flexible neoprene, especially around the shoulders and arms, which gives a much more natural swimming movement and reduces fatigue in the upper body. This can be felt, especially over longer distances. The cheaper wetsuit typically has slightly thicker and less elastic neoprene here, which can feel more restrictive – especially if you have an active swimming style.

Buoyancy also plays a big role. More expensive suits often have zones of varying neoprene thickness, so the suit lifts the body optimally: the hips and legs are raised to get you in a better swimming position, while the upper body remains more free and natural. The cheaper wetsuit typically has a more uniform neoprene distribution, which still helps with buoyancy - just not quite as precise or balanced.

The surface treatment is a third important difference. The most expensive suits use smooth, water-repellent coatings that minimize friction and provide high speed through the water. This is felt both as a lightness in the body and in your time on the clock. In cheaper wetsuits, the surface is usually more porous and uneven, which creates a little more resistance in the water.

Finally, there are the details: seams, zippers, cuffs, neck closures and interior panels. The expensive wetsuits are often glued and sealed with great precision, making them more durable and comfortable – and far less likely to take in water. The cheaper models are still functional, but you can expect a little more chafing and a little less finesse.

When you invest in an expensive wetsuit, you’re paying for performance in the water. It’s not just about seconds on a stopwatch – it’s about how you feel in the water. A top-of-the-line wetsuit gives you the freedom to move naturally, buoyancy that helps your technique, and a lightness that keeps your energy up all the way to the change. This is especially noticeable in competitions where intensity and precision count – or if you swim frequently and want to avoid unnecessary wear and tear on your shoulders.

Conversely, a more affordable wetsuit is a great choice for beginners, exercisers, and those who don't necessarily swim every week. You still get buoyancy, warmth, and a technical piece of equipment to help you get through the swim safely. You just compromise on flexibility and hydrodynamics – and maybe a little comfort.

At Transition Zone we are happy to help you choose the right wetsuit based on your needs, level and body type. We have both Sailfish and ZONE3 in our range – two brands known for high quality and a wide range of models. This means that you will find both solid beginner suits and top models with all the best neoprene the market has to offer.
