SLi Speed Suit



The complete triathlon suit for Ironman

An absolute high-performance suit developed and optimized in collaboration with athletes from the absolute world elite. For both women and men.

The SLi Speed Suit gives you the ultimate race suit that takes into account all conditions - whether you are an age group or a pro. The suit has been meticulously worked on in the technical details and marginal gains that can optimize your opportunities and make a measurable difference on race day.

Swimming: The flexible top provides great freedom of movement and the water-repellent legs improve your swimming. And when you get out of the water, your suit dries in minutes.

Cycling: The panels in the top material are tight-fitting, completely without folds, and very aerodynamically smooth. The material is actively cooling when wet, thus preventing rising body temperature. At the same time, the panels have an extremely high sun protection factor against burning. The sleeves are in a special aerodynamic design while the back pocket in its construction is also aerodynamically optimized.

Running: The material on the suit`s legs is woven to achieve true 4-way stretch and a sports compression of 12-10 mmHg pressure, which delays muscle fatigue. The special FUSION side pockets help you store the right amount of sports nutrition for the entire run without interfering with your movement pattern.

The composition of materials in the race suit, together with the elastic zipper, gives a very high formability, which means that the suit is not felt, and the resistance to movements is at an absolute minimum - among other things, the special micro-mesh panel on the front ensures that the pressure on the stomach is minimized as much as possible, so breathing is unobstructed.

The suit has a swim/bike/run constructed skin that provides good comfort on the bike ride without being bothersome on the run.

The suit is developed in materials that allow for the attachment of sponsor logos without changing the suit`s performance.

The weight is 191g in size medium.

Important features

FUSION Powerlock

The small red thread found in our products is not just for decoration but a guarantee of durable stitching. It's called a "trense" and, along with other types of lockstitches sewn in the material's color (and therefore less visible), it serves as a mark of quality craftsmanship. Approximately 20% of the time it takes to sew a pair of tights is spent on lockstitches – for example, there are over 30 of them in a pair of tights.

Soft and Elastic Fleece Pad for Cycling Comfort

The suit features a swim/bike/run constructed pad that provides excellent cycling comfort without being bothersome during running.

Micro-Mesh Panel Enhances Breathability

The suit is designed with a special micro-mesh panel on the front, reducing pressure on the abdomen and improving breathability.

Sun-Protective Upper Section

The material on the white panels is a result of our SuperWhite technology. It is woven from ceramic threads with a titanium core, providing protection against UV rays while keeping heat out. The material actively cools when wet, preventing an increase in body temperature.

Quick-Drying Suit

We have also focused on the composition of materials that make the suit quick-drying, resulting in a significant reduction in weight in a short amount of time.

Water-Repellent Lower Section

The material in the suit's legs is water-repellent, and when combined with the highly mobile upper body and elastic zipper, it improves swimming performance.

Sports Compression Delays Fatigue

The suit's legs are woven with sports compression at 10-12 mmHg pressure, aiding in optimal blood flow and, consequently, maximizing performance. Muscle fatigue is delayed, and endurance is increased.

Best Fit with True 4-Way Stretch

The suit's material is developed with genuine 4-way stretch, meaning it contracts and stretches equally in all directions. This results in the best possible fit and flexibility.

Aero Pocket on the Back

The construction and closure of the back pocket are optimized for aerodynamics. The elastic material ensures that the contents remain close to the body without discomfort.

Elastic Silicone Grip on Sleeve and Leg Cuffs

Free-cut bands with elastic silicone grip on the sleeve and leg cuffs keep the suit in place smoothly and securely on the body.

The Original FUSION Pockets

The functional Fusion pockets on the thighs keep their contents close to the body. Years of testing and user feedback have led to the unique placement of these pockets, ensuring minimal disruption to your range of motion during activity. The distinctive edge tape, which is soft, secure, and elastic, ensures that everything stays in the pockets.

Aero Sleeves

The suit's sleeves feature a specially designed aerodynamic profile.
