Castelli Nanoflex Arm Warmer Sleeves Red

HOW CAN THIS BE SO? Every day we try with all our strength to obtain innovative and performing products, and sometimes we are surprised even ourselves. NanoFlex fabric behaves exactly like our Thermoflex fabric when the weather is dry, but when it starts raining it is incredibly water-repellent. We do not claim that it is impermeable to 100%, but it is one of the innovations that has worked best to give you a comfortable solution in different weather conditions. It is almost a miracle.
