Castelli Viva Thermo Skully

When your head gets cold, you lose the ability to monitor what is happening with your body. You need to function 100% in every way when you ride your bike. So, if you want to handle a ride when the days get cold, you will need to cover your head under your helmet. The Castelli Viva Thermo Skully will do this. It is a one-size-fits-all cap, lined with Thermoflex, which will keep the cold out and wick the sweat away. The cap is cut so that it covers your head completely and fits comfortably under your helmet.
