// The development of our brand new the AERO CALF Sleeves involved extensive research and testing. Our aerodynamics team took a pioneering approach by constructing an in-house wind tunnel dedicated solely to textile research. This innovative facility, designed specifically for this project, enabled precise and detailed testing of over 150 samples. In collaboration with industry textile experts COLAB, the Swiss Side team rigorously evaluated the performance of the AERO CALF Sleeves at various speeds and angles, ensuring optimal drag reduction on different leg shapes.

These sleeves are designed to reduce air drag to save up to 8 watts on the bike course of triathlon competitions. Suitable for all triathlete types they offer a non-compressive aero fit for easy application and removal during transitions.
