Collection: Wetsuit & Open Water

When it comes to open water swimming, a wetsuit isn’t just a necessity – it’s a game-changer. Whether you’re training for your first triathlon or are an experienced open water swimmer, your wetsuit plays a crucial role in comfort, warmth and performance. The right wetsuit helps keep you warm, increases your buoyancy and improves your water position so you can swim more efficiently and save energy.

At Transition Zone, we only stock wetsuits from Sailfish and ZONE3 – two of the world’s leading brands in triathlon and open water. Developed with input from elite swimmers and tested in competition, their wetsuits combine cutting-edge materials, flexibility and buoyancy in one design. This means you get a suit that feels comfortable and helps you perform at your best – no matter your level.

Sailfish is known for their uncompromising approach to design and fit. Their wetsuits are among the most popular in both Europe and globally, and they are particularly loved for their flexibility and natural freedom of movement. Suits like the Sailfish One and Sailfish Attack are designed for triathletes who want a combination of speed and comfort - perfect for both competition and training.

ZONE3 is a British brand that has quickly gained cult status among open water swimmers and triathletes. They are known for delivering high performance at a competitive price, and their suits are packed with technical features such as Yamamoto neoprene, buoyancy zones and low friction surfaces. The range ranges from beginner-friendly models like the Aspire to advanced competition wetsuits like the Vanquish - all designed for maximum efficiency in the water.

Both brands have models for both men and women, and all suits are tested for both open water and triathlon. Whether you're new to the sport or aiming for a PR at your next Ironman, you'll find a suit to match your goals.

Choosing a wetsuit depends on several factors: your experience, your swimming style, and where – and when – you swim. Here are some key points to keep in mind:

Buoyancy and position: Some swimmers need extra buoyancy in the hips and legs, while others prefer a more neutral suit. Suits from Sailfish and ZONE3 offer both, so you can find the type of buoyancy that suits your particular swim.

Flexibility: If you have a strong swimming technique, you will probably prioritize flexibility in your shoulders and arms. The best models combine flexibility with low friction for optimal glide through the water.

Fit: A wetsuit should fit snugly without being too tight. It should not bunch or pull over your shoulders. Take some time to try on different sizes, or stop by our store – we will be happy to help you find the perfect fit.

Water temperature: Most suits are suitable for temperatures between 14-24°C, but some models have extra thermal protection for cold conditions. If you are swimming in early spring or late autumn, this can be an important factor.

At Transition Zone you won’t just find a selection of wetsuits – you’ll find products we stand behind. We’ve chosen Sailfish and ZONE3 because we know their suits work in the real world. It’s equipment you can trust in training, competition and open water – tested and loved by triathletes and swimmers all over the world.

We offer personal guidance both online and in store, and you are always welcome to come by and try the suits on before you decide. If you have any questions about fit, buoyancy or which model is right for your level, we are ready with advice and experience. And of course we also have open water accessories such as buoyancy aids, neoprene gloves, socks and caps – everything you need to make your swim safe and comfortable.
