SLi Speed Suit

Regular price 2.034,00 kr

For the experienced triathlete who wants to go further. Uncompromising triathlon competition suit for 70.3 and IM distances. Developed and optimised in collaboration with athletes from the absolute world elite.

SLi SPEEDSUIT is the ultimate race suit that takes all conditions into account – whether you’re an age grouper or a professional. The suit is meticulously designed in its technical details and marginal gains, which optimises your chances and can make a measurable difference on race day.

Swim: The flexible upper provides great range of motion, and the water-repellent legs improve your swim. And when you leave the water, your suit dries quickly.

Bike: The top panels are snug, completely fold-free and very aerodynamically smooth. The fabric is actively cooling when wet, preventing rising body temperature. At the same time, the panels provide extremely high solar protection against sunburn. The sleeves feature a special aerodynamic design, while the back pocket is also streamlined in its design.

Run: On the legs of the suit, the material is woven to achieve genuine 4-way stretch and 10–12 mmHg sports compression that keeps muscle fatigue away. The special FUSION side pockets help you store the right amount of sports nutrition for the entire run without hindering your pattern of movement.

The combination of the materials in the race suit, together with the elastic zip, makes the suit highly form-fitting, which means you hardly notice it and movement resistance is at an absolute minimum. The special micromesh panel on the front, for example, ensures that the pressure on the stomach is reduced as much as possible, so breathing is unobstructed.

The suit is made with materials that allow the application of sponsor logos without any change in the suit’s performance.

Like all our other triathlon suits, this suit has a swim/bike/run friendly chamois that provides excellent comfort on the ride, without getting in the way on the run.

The weight is just 191 g in size medium.

Some good advice on how to extend the life of your FUSION sport garment

  • Wash you sports clothing at a maximum temperature of 40° C. Do not use detergent and do not bleach.
  • Use of detergent will limit the moisture-transport of the product. Therefore do not use detergent.
  • Hang-dry your FUSION sports garment. Do not tumble-dry.
  • Be aware of sharp items, edges and Velcro straps on backpacks, belts and likewise, rubbing against fabric and seams of you garment. It may rip both fabric and seams of your FUSION sports garment.
