The Castelli Flight Jacket Air is designed to regulate your core temperature and prevent overheating, whether you're cycling intensively or riding in the cool morning air. It features thin yet insulating padding on the chest, sleeves, and upper back, combined with a water-repellent outer layer that blocks wind while allowing sweat to escape.

This jacket is made with Nano Flex Light fabric and Polartec® Alpha® insulation, making it perfect for days when a regular jersey won't do but a fully weatherproof jacket is too much. It offers moderate protection while remaining lightweight and breathable, providing warmth without hindering your performance.

With sleeves that can be stretched over or tucked into gloves, a short cut to prevent bunching, three spacious pockets, and reflective detailing at the back, this jacket is versatile and ideal for transitional seasons.
