Castelli Insider

The lightest and coolest shorts for indoor training. If you mainly train indoors during the winter months, a special indoor short can provide the desired cooling effect. The entire construction of these shorts is designed to make them as cool, light and airy as possible while providing the necessary muscle support. The main material is lighter than race shorts and the side mesh inserts provide additional ventilation. Use the top layer of the proven Progetto X2 Air Donna Seamless chamois, as this is sufficiently padded for most indoor sessions, but much cooler than a full Progetto X2 Air Donna Seamless chamois, as in outdoor cycling shorts. 195 g/m² heavy Lycra® material on the body - just right for the necessary support and opacity. Mesh side panels for good ventilation. Raw cut leg cuffs for a non-slip fit. Seat pad with Progetto X2 Air Skin Donna top layer.
