Castelli Aria 2 Vest - Women's Silver Gray, M

What Our Gearhead(R) Experts Are Saying:"The Aria 2 Vest disappeared into my jersey pocket on the way up and came right back out on the descent, and at 85 grams, I genuinely forgot it was there until I needed it. The windproof front kept the chill off my core without making me feel like I was overheating once the road flattened back out."The Aria 2 Vest from Castelli is the answer to that very specific problem every cyclist knows well: the climb is warm, the descent is not. At just 3 ounces, it packs down small enough to live in a jersey pocket all ride long and comes out exactly when you need it without slowing your momentum at all. The tailored fit sits close to the body so it moves with you rather than flapping in the wind, which matters when you are already moving fast. Windproof fabric across the front blocks the chill where your core needs it most, while the stretch breathable back panel keeps air moving so you do not cook on the next effort. That balance between protection and ventilation is what makes the Aria 2 Vest useful across a wide range of conditions rather than just a single weather scenario.
