Aria 2 Vest - Men's

What Our Gearhead® Experts Are Saying:

"I throw the Aria 2 in my jersey pocket whenever there's a chance of wind or cool descents. It blocks the chill on the front but doesn’t trap heat thanks to the mesh back. Super stretchy and light, and it folds down smaller than my gloves. Absolute staple for shoulder-season riding."

For those brisk morning rollouts and fast alpine descents, we pack along the Aria 2 Vest. This ultralight wind shell packs serious protection into a featherweight design, blocking wind on the front while letting our body breathe through the stretchy mesh back. It's the layer we barely notice—until we need it.

With a form-fitting cut and high-stretch fabric on the back and sides, the Aria 2 stays put without flapping in the wind. It disappears into a jersey pocket when the sun rises or the climb begins, and the dual-slider zipper lets us dump heat without removing the vest entirely. Whether it’s your first layer or your fail-safe backup, the Aria 2 delivers adaptable coverage for the in-between days.
