What distinguishes them?

The development of the AERO CALF Sleeves involved extensive research, testing, and development. Our aerodynamics team took a pioneering approach by constructing an all-new in-house wind tunnel facility at the headquarters, with special functionality dedicated to sports textiles R&D. This enabled high-precision and efficient testing of over 50 fabric types in 135 different configurations.

By doing so, we were able to ensure the maximum performance benefit for the widest range of athletes in any conditions. 92% of all athletes tested confirmed robust aero drag savings, solely wearing the AERO CALF Sleeves. Accordingly, savings of up to 8 watts at 45km/h were achieved. The performance benefits extend consistently also to lower and higher speeds.

Revolutionary in R&D of textiles

The AERO CALF Sleeves are deliberately designed with a non-compressive fit to prevent any unintended physiological performance detriment when riding. This feature also allows for quick and easy application during the transition in non-wetsuit races. Recognizing the significance of comfort and thermal management in triathlon, the AERO CALF Sleeves incorporate breathable and high-cooling base fabrics, to facilitate optimal ventilation and temperature regulation, enabling athletes to perform at their highest level in all conditions. Wondering why the sleeves don't have fancy colors or designs, it is indeed a performance-driven decision, as the fabric sublimation process negatively impacts both the aerodynamic performance and breathability of the fabric.
