Overview Description.
The Aria Vest has always been one of the most versatile pieces in our collection.
Now, it´s even better.
We´ve refined the fit for a more ergonomic shape and added reflective elements with our updated logo and wordmark, enhancing visibility while keeping the aesthetic clean and modern.
It blocks wind where it matters most, breathes through mesh side panels, and fits close to the body, thanks to stretch inserts on the sides and shoulders — no flapping, no drag, no bulk.
It´s the ideal layer for cool starts, long descents, or unpredictable weather, and when things heat up, it packs down into its own pocket to disappear into your jersey pocket or saddlebag.
