Zone3 Aeroforce-x Ii Calf Warmers Black / Red M male

The Aeroforce-X II Aero Calf Sleeves are engineered to deliver meaningful aerodynamic efficiency gains on the bike, targeting the lower leg, a known source of aerodynamic drag. Manufactured by NOPINZ, specialists in aerodynamic performance apparel, they are designed for race-day use where marginal gains matter most.Developed in collaboration with NOPINZ, leaders in aerodynamic garment engineering, the Aeroforce-X II Aero Calf Sleeves are designed to optimise airflow around the calf during high-speed riding. The lower leg contributes significantly to aerodynamic drag, and refining airflow in this area can improve overall riding efficiency over race distance.The sleeves use a lightweight, quick-drying technical fabric engineered to support controlled airflow while remaining breathable at race intensity. Integrated mesh zones promote ventilation and temperature regulation without compromising the aerodynamic profile. A close, contoured fit creates a smooth interface with the leg, helping reduce turbulence without restricting movement.A silicone gripper at the upper cuff ensures the sleeves remain securely in place throughout the bike leg, maintaining consistent positioning from transition to dismount. Designed exclusively for competition, the Aeroforce-X II Aero Calf Sleeves reflect NOPINZ's race-proven approach to aerodynamic performance.Key Features & Benefits:- Manufactured by NOPINZ: Developed by specialists in aerodynamic performance apparel.- Lower-Leg Aerodynamic Optimisation: Designed to reduce airflow disruption around the calf for improved efficiency on the bike.- Airflow-Engineered Fabric Construction: Supports controlled airflow at speed without compromising comfort.- Lightweight, Quick-Dry Performance Fabric: Minimises water retention and supports race-day comfort.- Breathable Mesh Zones: Promote ventilation and temperature regulation during sustained efforts.- Precision Race Fit: Contoured shaping designed to sit smoothly on the lower leg without restricting movement.- Silicone Upper Gripper: Maintains secure positioning throughout the bike leg.
