Castelli Summer Skullcap

Keep your head cool and your vision sharp throughout every high-intensity ride in the sun! If you want to avoid getting annoying drops of sweat in your eyes while cycling, the Castelli Summer Skullcap is a must-have accessory for you. Thanks to its minimalist design and ultra-light materials, you will hardly notice you're wearing an extra layer under your helmet.

Fabric and fit
The Summer Skullcap is specifically designed to fit like a second skin under a cycling helmet without noticeably adding volume. The top features a strategically placed mesh panel that ensures constant airflow and maximum breathability. This effectively prevents heat build-up and makes the cap highly suitable for summer temperatures above 20°C. The close fit keeps the cap well in place and the lightweight fabrics minimise irritation on long endurance rides in the heat.

Smart extras and high-quality finish
The main asset of Castelli's Summer Skullcap is the absorbent layer that serves as a sweat barrier. It rapidly wicks moisture away from your forehead, preventing salt and sweat from getting into your eyes or cycling glasses. With a weight of just 21 grams, this is one of the lightest accessories in the headgear segment. The finish is flat to avoid distraction while cycling due to pressure points with the helmet liner. Plus, the fabric is quick-drying, so after a short break the cap feels dry and comfortable again. Enjoy your summer rides!
