The Castelli Aria Vest is a high-performance cycling vest engineered to provide essential wind protection and lightweight versatility for a wide range of riding conditions. Designed for riders who want an efficient barrier against cool headwinds without unnecessary bulk, the Aria Vest blends aerodynamics, breathability, and packability to support fast efforts, long rides, and ever-changing weather. Its streamlined fit follows the rider’s posture on the bike, reducing drag while maintaining unrestricted movement and comfort.

Built with Castelli’s advanced stretch-woven windproof fabric, the Aria Vest blocks wind across the chest while remaining highly breathable, helping you maintain core warmth without overheating during sustained efforts. The soft, stretchable material conforms to your shape and motion, minimizing flapping at high speeds and enhancing the vest’s performance feel. This balance of protection and airflow makes the Aria Vest ideal for cool mornings, windy descents, or as a layering piece when temperatures fluctuate.
