Castelli Aria 2 Vest Men's Ultralight Packable Wind Cycling Gilet

The Castelli Aria 2 Vest is an ultralight windproof cycling gilet designed to provide effective wind protection while maintaining excellent breathability during road rides.

The updated Aria 2 generation improves ergonomics, fit and riding stability while reducing the typical flapping effect of traditional cycling vests.

Wind protection without overheating

The front panel effectively blocks wind during descents and cool morning starts, while the stretch mesh rear section improves airflow and temperature regulation.

This balance makes the Aria 2 Vest especially versatile for spring and autumn riding or routes with changing temperatures. 

Lightweight and packable

With a claimed weight of approximately 89 g, the vest folds into its integrated stuff sack and takes up minimal space inside a jersey pocket or saddle bag. 

Many cyclists particularly appreciate lightweight packable gilets for adapting quickly to changing weather conditions during long rides. 

Fit and comfort

The stretch side and shoulder panels help the vest fit closely to the body, reducing aerodynamic drag and fabric flapping.

The Tailored Fit is designed to layer comfortably over fitted cycling jerseys without feeling excessively loose.
