Created to manage the rigors of hot weather riding, the ASSOS roboFoil is an ultra light cycling cap. An intelligent accessory, this riding cap helps manage heat and sweat build up when worn underneath a helmet. Made to be as light as possible, it uses two different fabrics to perfectly contour to your head. Cleverly joined flat seams provide for minimal volume, no pressure points, and total comfort. Providing an antibacterial interface between your head and helmet, it’s a small accessory, but one which makes a huge difference to your comfort. The roboFoil keeps you head cool, stops sweat dripping in your eyes, and gives protection from the sun. What more could any cyclist want?
