DISCOVER OUR NEWEST TRIATHLON SUIT

There's no room for compromise in endurance sports. When designing apparel to meet the extreme demands of triathlon, our decision-making process always begins with a single question: how can we gain extra seconds without sacrificing a fraction of comfort? The answer lies in the uncompromising selection of innovative solutions and the combination of aerodynamic materials manufactured using the latest technologies.

We've created a product that pushes the boundaries. It's the fastest and most comfortable wetsuit on the market.

STRUCTURAL ENGINEERING DRAG MINIMIZATION

Aerodynamics embedded in the structure

The key to squeezing precious minutes on the bike is minimizing air resistance. This new model features advanced materials with a unique texture. The special ribbed detailing and diamond structure on the shoulders and sleeves aren't just a visual effect—they're precisely engineered textiles.

Their function is to break up the airflow flowing around the body and generate microturbulence, which dramatically reduces aerodynamic drag (CdA). Every watt saved on the bike course is energy you can use on the run.

Smooth profile and hidden pockets

Many athletes face a dilemma: aerodynamics or access to supplements? We've solved that dilemma.

We've done away with traditional external back pockets, which act like small parachutes and restrict airflow. Instead, we've introduced an innovative internal pocket system.

This solution guarantees a completely smooth back profile. You can access your gels and bars in a split second by gently unzipping the front zipper, while airflow around your body remains unimpeded.

100% Smooth back profile No external pockets to disrupt the flow of the stream

Instant access to gels. Intuitive hand movement in a split second.

Elimination of the parachute effect. Suit stability even in strong crosswinds.

Reliability in the transition and finish zones

Details make all the difference. We've equipped this suit with a reinforced, reliable zipper from the renowned YKK brand.

What's more, we have introduced a special safety solution: the zipper is designed and finished in such a way that it does not open automatically below the permitted limit.

This way, you avoid the risk of accidentally breaking the judges' rules at the finish line and facing disqualification. You focus solely on the distance—the equipment takes care of the rest.

ERGONOMICS 226 HP · ZERO PRESSURE POINTS

A design refined in every detail

Comfort over the full Ironman distance is built on the absence of any pressure points. In this model, every element has its absolute justification:

Sleeve cuff finished with speckled silicone Sleeve & Shoulder

Sleeves finished with speckled silicone

They hold the fabric perfectly in place in an aggressive aero position, eliminating bunching without feeling tight on the shoulder.

Secure aero grip. Zero creasing. No pressure.
The most comfortable leg in your outfit

Ultralight knit fabric and leg finishing

The lower legs are made of a technologically advanced knit fabric integrated with a wide strip of silicone micromesh directly into the fabric structure. See the video above: no sewn-in tape, no bulky seams on the cuffs, no rolling up while running or riding, maximum breathability, and a smooth second-skin transition.

Active Seam Hybrid Seams and Panel Welding in a Triathlon Suit Hybrid Integration

Hybrid Joints: Active Seam and Welding

Where the suit works with your body, we've used state-of-the-art, stretchable Active Seam seams. In critical areas, we've opted for welded (glued) seams that create perfectly flat seams, preventing chafing even after nine hours of grueling activity.

Dedicated professional triathlon pad Elastic Interface Heart of the Outfit · Insert

Dedicated triathlon insert

The heart of the suit is the professional Elastic Interface® pad. Designed to provide maximum support and cushioning in a deep saddle position, while remaining completely invisible and unnoticeable during marathon running. It doesn't absorb water, dries quickly after exiting the water, and doesn't restrict stride biomechanics.
