CASTELLI AERO RACE 5.1
Sizes XS-XXL Colours Anthracite/white, Dark Infinity Blue, Forest Grey Weight 110g (S)
This jersey is aimed at racers looking for clothing made from the fastest windcheating materials to save every last watt. It’s lightweight with a race cut but remains comfortable and uses aerodynamic dimpled fabric up front. On the arms and rear Castelli uses its breathable 3D mesh fabric that performs brilliantly in the heat. Other neat touches include long aero sleeves, a low collar, an easy-grab zip extender and three decent pockets. The 5.1 fits and sits well, and has proved durable despite feeling delicate. It’s among the best aero jerseys we’ve tested.
