For riding in temperatures as low as zero degrees celsius, the Castelli Women’s Sorpasso Waist Tights are a great choice. The high waist band, ankle grippers and shoe cover seal ensure that there are no gaps for air to sneak in as well as securing the tights in place so they don’t slip down or up whilst you’re in full force. They also have a layer of fleece lining for extra warmth and a padded bum to protect you from chaffing on long rides.
