Collection: Wetsuits for Swimming and Triathlon

A good wetsuit is not just a piece of neoprene – it is one of the most important pieces of equipment for any triathlete or open water swimmer. The right wetsuit improves your position in the water, increases your speed and keeps you warm in cold temperatures. Whether you are training for your first triathlon or chasing seconds in an Ironman race, your wetsuit is essential to your experience and performance in the water.

At Transition Zone, we carry carefully selected wetsuits from two of the most recognized brands in the triathlon world: Sailfish and ZONE3. Both brands are known for their high quality, technical innovation and comfort – and we have models that suit both beginners and experienced athletes. What all the suits have in common is that they are created for performance – with a well-tested fit, flexible neoprene and smart details that help you both in and out of the water.

Unlike diving suits, swimming and triathlon wetsuits are designed with one purpose in mind: to optimize your open water swimming. This means low weight, high flexibility and strategically placed buoyancy. Most triathlon wetsuits are made from Yamamoto neoprene, which is known for its flexibility and minimal water resistance.

Here are some of the technical features you can expect in a good triathlon wetsuit:

Buoyancy panels: Keeps you in a streamlined position so you use less energy.

Thin shoulder and arm sections: Provides maximum freedom of movement and reduces fatigue.

Hydrophobic surface treatments: Reduces friction and increases speed in the water.

Lightweight zipper and quick-release cuffs: Make it easy and quick to get out of the suit in T1.

These features mean you swim faster, use less energy – and have more energy for the rest of your race.

At Transition Zone, we have chosen to exclusively carry wetsuits from Sailfish and ZONE3 – two brands with strong roots in triathlon and countless test-winning models behind them.

Sailfish is a German brand founded by former professional triathlete Jan Sibbersen. Sailfish is known for its uncompromising quality, extreme flexibility and precise fit. Suits like the Sailfish One and Sailfish Attack are ideal for both competition and training – and popular with both beginners and elite athletes. Many particularly highlight Sailfish for its tight but comfortable fit and for its superior feel in the water.

ZONE3 is a British brand that has become world-renowned for their user-friendly and technically advanced suits. With models like the Advance, Aspire and Vanquish, ZONE3 covers the whole spectrum – from first triathlons to world championships. Their suits combine high buoyancy with extreme mobility, making them particularly suitable for longer distances.

Whether you choose Sailfish or ZONE3, you'll get a suit created by people who compete themselves – and who know what it takes.

We know how important a good wetsuit is – both for your confidence and your experience in the water. That’s why we only sell models that we stand behind and that have been thoroughly tested by triathletes and open water swimmers. Whether you’re heading towards your first 1500m or planning an Ironman, we have a suit to suit you.
