Description
Lightweight, fast and aerodynamic; introducing Castelli's Aero Race 5.1 Full Zip Short Sleeve Jersey. Perfect for both training and racing on hot summer days, you'll be able to save up to 22 watts when riding at 40km per hour in comparison to a standard jersey, which could make all the difference to your position come race day.
With a close, race fit, and thanks to the Velocity dimpled fabric on the front, 3D mesh on the back and mesh arm bands, this jersey is highly breathable and will wick sweat away to keep you dry and prevent overheating.
Silicone gripper elastic on the hem keeps the jersey securely in place and a full-length YKK zipper adds to the versatility, allowing you extra ventilation when you're working hard. Three rear pockets are easily accessed mid-ride and offer plenty of space for tools, nutrition and other ride essentials. Reflective heat-transfer visibility strips on the lower back ensure other road users will see you in plenty of time.
