Castelli Cafe on the Castelli Converter Cap; First off this isn't a cap basically this is a tube of soft fleece with a toggle and drawcorp closure at one end. It makes a great neck and face warmer in cold conditions and can be worn as a hat with the toggle done up (Warning: it wont fit under your helmet).
The reversible colourways means you can choose safety or discreet style with just the one garment. Unisize too makes this an ideal gift for cycling friends and family.
