The Aria Vest jacket has always been one of the most versatile pieces in our collection. Today it is even more so. We have refined the fit for a more ergonomic shape and added reflective details with our new logo and wordmark, improving visibility while maintaining a modern, clean line. It blocks the wind where it's most needed, is breathable thanks to the side mesh panels, and conforms perfectly to the body thanks to the elasticized side and shoulder inserts: no fabric flapping, no wind resistance, and no bulk. It's an ideal layer for cool morning starts, long descents, or unpredictable weather; and when the temperature rises, you can pack it into its own stuff sack and make it disappear into a jacket pocket or saddlebag.

Ultralight. Maximum functionality. Indispensable, for every ride.
Our lightest, packable wind vest that conforms to the body thanks to the elasticized breathable fabric back.
