The Summer Headband is made to be super low profile so it will fit under your helmet and be soft against your forehead for comfort. Castelli has achieved this by creating a construction technique that eliminates the trim around the edge to make this sweatband as soft as possible while keeping the volume of the headband down as close to zero as possible.
Castelli's proprietary poly fabric does a solid job at keeping sweat from your eyes and dripping down your face during efforts. Beyond these duties it is quick drying and ultra vented. The width and amount of elastic used in the headband has been perfected over the past few season to optimize comfort and performance. Clearly one of the best summer headband designers we have seen to date. One size fits all, choose color.
