None of us want sweat dripping in our eyes. But none of us want to wear head gear that will leave a deep indentation circling our heads after a long, hot ride, either. The Castelli Summer Headband is so soft against your forehead, that you won't even remember you are wearing it. It has a non-aggressive hold that will prevent any potential indentations. The poly fabric is tailor made to wick sweat away from your forehead, keeping it out of your eyes.
The Castelli Summer Headband has a Uni Size, which means that it will fit you unless you have a head the size of a newborn baby or a rhino. It comes in Black/White, so will surely match all your other Castelli items.
