Aerodynamic Innovation

The Castelli Fast Legs Sleeves are designed using the same wind tunnel technology used by Formula 1 racing teams. By creating micro-turbulence at the front of the calf with unique structures, air resistance is significantly reduced. This results in proven aerodynamic benefits and a power gain of seven to eight watts, which saves significant time over long distances such as an Ironman race.

Ultralight Ventilation and Comfort

The ultra-light fabric around the calf provides high-quality ventilation, keeping you cool during competitions in warm conditions. The breathable materials provide optimal comfort, so you can focus on your performance without being distracted by discomfort.

High Quality Muscle Support

The Fast Legs Sleeves provide targeted 360-degree compression, providing high-quality muscle support for the calves. This reduces the risk of injuries and cramps, allowing you to perform longer and more comfortably. Whether you participate in an intensive cycling race or a long triathlon, these sleeves effectively support your muscles and help you achieve your goals.
