What Our Gearhead(R) Experts Are Saying:"I never ride without the Summer Headband when temps climb. It keeps sweat out of my eyes, fits perfectly under the helmet, and stays cool and light even on big climbs. You forget it's there-until you realize you're not wiping your face every five minutes."When the heat's up and the pace is high, we need small details to work overtime. The Castelli Summer Headband is one of those unsung heroes-keeping sweat in check so we can focus on the ride ahead. It's low-profile, breathable, and built to disappear under a helmet while doing exactly what it's designed to do. The front panel uses moisture-wicking polyester stretch fabric to absorb and disperse sweat, while the rear stretch-mesh panel promotes airflow and keeps the fit snug without pressure. Simple, lightweight, and essential for summer mileage, the Summer Headband makes every hot-weather ride just a little easier.
