The Castelli Espresso Armwarmer is built for cyclists who demand warmth and comfort on chilly rides. Made from soft Espresso thermal fabric, this armwarmer provides insulation to keep muscles warm in cold conditions. The single-piece construction eliminates unnecessary seams, ensuring a smooth and irritation-free fit, while the silicone gripper prevents the armwarmer from sliding during high-intensity rides. Ideal for road cyclists navigating seasonal transitions, the Espresso Armwarmer is a practical and stylish accessory for cooler days.
