Castelli - Diverso 2 18
The Diverso 2 18 Socks are the thickest and warmest of Castelli's range of socks. Merino wool gives the socks a fantastic warmth to weight ratio and they retain heat even when damp. The modern fibres used give the socks stretch and add to the overall comfort. With an 18cm cuff, they're a great length for winter, adding an extra layer of warmth under tights or leg warmers.
