Aria Shell 2 Jacket delivers windproof protection with stretch vent panels for comfort
What Our Gearhead® Experts Are Saying:
"This jacket is light, windproof, and packs super small. I barely notice it when it’s stashed, but I’m always glad I have it on cool descents. The fit is race-cut, and the stretchy panels keep it from feeling restrictive or flappy. A top-tier packable shell for fast rides."
The Aria Shell 2 Jacket brings race-ready fit and wind-blocking performance together in a streamlined, packable shell that’s ideal for variable conditions. Built with ultralight woven microfiber, the front and sleeves act as a windproof barrier during cold rollouts and gusty descents. At the same time, striped mesh side panels and stretch zones on the back of the sleeves ensure breathability and mobility, even at tempo pace.
The tailored silhouette reduces bulk and eliminates flapping, keeping the jacket close to the body for efficient aerodynamics. A two-way YKK® Vislon® zipper allows ventilation control mid-ride and adds convenience when accessing jersey pockets underneath. When the sun rises or the climb begins, the Aria Shell 2 folds easily into its own integrated stuff sack for compact stowage.
With reflective logos for added visibility and a featherweight 109g construction, the Aria Shell 2 Jacket is a versatile, must-have layer for transitional seasons, early starts, and long, high-speed descents where protection and packability matter most.
