The Castelli Pro Seamless Leg Warmer was developed in collaboration with the INEOS Grenadiers with the aim to create a better seamless warmer for those in-between weather days.Damp kit is often uncomfortable and can hinder your performance. Many seamless warmers use a nylon/Lycra blend that tends to hold moisture, but Castelli resolved this issue by introducing polyester into the unique fabric used for the Pro Seamless Leg Warmer.Due to their breathability, and being extremely warm for their weight, the leg warmers have proven a pro rider favourite. When the warmers are on their high stretch means you hardly feel them, and when you take them off, they occupy a fraction of the space that normal warmers would take up in your pockets. Key Features: Mid weight seamless warmer developed with the INEOS Grenadiers,Warm without causing overheating,Unique polyester, nylon, Lycra blend (78%, 15%, 7%),Folds up extra small,Temperature comfort range of 10° – 20°C,Weight 74g (Pair).
