The origin of Fusion – created for driven athletes

Founded in 1999 in Denmark, Fusion has a clear mission: to develop sportswear that makes you measurably faster. Not with trends or marketing promises, but through science-based innovation, rigorous lab testing and direct feedback from elite athletes. From day one, Fusion has worked closely with professional triathletes, cyclists and runners to create apparel that’s not only comfortable, but that truly contributes to better performance in the toughest conditions.

What sets Fusion apart is an engineering mindset. Every product starts from pure functional necessity: minimal drag, maximum efficiency, optimal body temperature and full freedom of movement. On top of that, Fusion deliberately chooses European production and durable materials – because real performance only counts when it’s made responsibly, with respect for people and the environment.

What makes Fusion unique?

Every Fusion garment is produced end-to-end in Europe, in the brand’s own certified facilities, to maintain full control over quality, sustainability and working conditions. No mass production in low-wage countries – but deliberate, small-scale manufacturing with one goal: helping you perform better.

What truly sets Fusion apart:

Made in Europe

Fusion designs, produces and tests every step in-house. This guarantees consistent quality, short supply chains and zero compromises on sustainability or performance.

OEKO-TEX® certified materials

All fabrics are tested for safety and skin-friendliness. They are free from harmful chemicals and come from responsible European textile production.

Built to last

Fusion pursues sustainability through durability – not by talking about it, but by making garments that still perform perfectly after hundreds of washes.

Scientifically developed fabrics

The iconic C3 fabric is known for exceptional breathability and durability, while TEMPO! technology was developed in a wind tunnel to actively reduce aerodynamic drag on the bike and the run.

A second-skin fit

Fusion uses minimal seams, strategically placed compression zones and an anatomical cut that moves with your body. No chafing. No distractions. Just pure focus.

No-nonsense performance design

No unnecessary graphics or fleeting fashion trends. Everything you see serves a purpose. Fusion believes perfection is achieved not by adding, but by removing.

Fusion triathlon apparel – built for speed, sustained focus and top performance

In triathlon, every second counts – and so does every detail. Your tri kit shouldn’t just support you; it should actively help you move faster, breathe more efficiently and stay longer in your optimal zone. Fusion triathlon apparel is designed from scientific wind-tunnel measurements and elite-athlete feedback – whether you’re racing a sprint distance or a demanding Ironman.

Hydrodynamic & aerodynamic design

Fusion’s tri suits minimise drag in the water and maximise speed on the bike and run. Strategically placed panels streamline airflow, while water-repellent materials prevent the suit from becoming water-logged at the swim start.

Active compression & muscle support

Engineered fabrics in Fusion tri-suits provide controlled compression to reduce micro-vibrations, prevent energy leaks and optimise blood flow. The result? Less fatigue build-up and more focus throughout your race.

Temperature regulation in all conditions

Triathlons are won by the athlete who stays coolest. Fusion fabrics actively regulate body temperature – from hot, sun-baked courses to cooler European races. Mesh zones boost ventilation, while protective layers (UPF 50+) shield your skin.

What you’ll find in the Fusion triathlon range

• Tri suits (one-piece TEMPO! series): engineered for pure race speed, with aero sleeves, integrated nutrition pockets and an Italian fleece chamois that’s comfortable on the bike and unobtrusive on the run.
• Tri tops and shorts (two-piece systems): flexibility for athletes who prefer separate upper and lower pieces with the same aerodynamic properties.

Fusion’s triathlon apparel is specifically developed for both men and women, with fits tailored to anatomical differences for maximum aerodynamics, comfort and freedom of movement. Whether you choose a men’s tri suit or a women’s tri suit, you benefit from the same high-performance technologies, durable materials and scientifically validated designs.

Fusion cycling apparel – control, power and support on every ride

Cycling isn’t a sport of comfort; it’s a sport of control. Fusion cycling apparel is designed to give you that control – in your position, your temperature and your energy management. Every piece is developed with professional cyclists and tested under race intensity, long-distance training and variable weather.

Features that make the difference:

• Aerofit cut: a close, streamlined fit that reduces drag and transfers power directly to the pedals.
• Muscle support: compressive panels stabilise muscles, reduce fatigue and improve blood flow during long efforts.
• Advanced temperature management: technical fabrics move sweat away fast, keep you dry and regulate heat.

Built for every discipline

Road, gravel or indoor on the smart trainer – Fusion offers cycling apparel that adapts to your effort and environment so you can perform without distraction.

What’s in the Fusion cycling line?

For men:

• Cycling jerseys
• Bib shorts
• Long cycling tights
• Cycling jackets

For women:

• Bib shorts

Important: Fusion designs distinct lines for men and women. The fit isn’t only visually different; it’s anatomically optimised for riding posture, pressure points and thermoregulation – for a perfect fit and maximum performance.

Fusion running apparel – efficiency, temperature control and maximum freedom of movement

Running is about rhythm, focus and control over your body. Fusion running apparel is designed to support that rhythm, kilometre after kilometre – whether you’re training for a 5K, a marathon or an ultra. All fabrics are engineered for exceptional moisture transport, thermoregulation and long-term comfort, even during your hardest sessions.

Performance benefits you feel with every step:

• Optimal temperature regulation: keeps you cool in heat and warm in cold – without overheating.
• Quick-dry, breathable materials: move sweat away from the skin to prevent irritation and chafing.
• Ergonomic fit with minimal seams: follows your movement, supports your muscles and avoids distractions.
• Built for performance: everything Fusion makes has one goal – to improve your run performance.

Fusion running for men

Fusion offers a wide range for men, so you’re equipped for any conditions.

• Running jackets: protection from wind and rain without overheating
• Long running tights: compressive, thermoregulating and breathable
• Running singlets: ultra-light for maximum cooling

Fusion running for women

Specifically tailored to female anatomy, with dedicated fit and support:

Fusion running apparel is built on the principle of efficiency: less energy loss, fewer distractions, more speed. It’s gear you don’t think about while running – because it moves perfectly with your body.
