Cycling during the cool weather months can be a big guessing game. Starting out you’re freezing! But once you get into your groove you’re on fire. How do you correct this imbalance? To make autumn and spring rides more manageable the creative minds at Castelli put their heads together as to how to make you stay warm even in chilly temperatures while also keeping cool after your body heat builds. After working with the professional Ineos cycling team they developed the Pro Seamless Knee Warmer to enhance your natural body heat without any unnecessary bulk.
