The Castelli Insider Shorts are sufficiently light and cool to keep you comfortable during your indoor training sessions.

The Lycra® that makes up the greater part of the shorts is extremely stretchy, ensuring a great fit, while also being highly breathable and moisture wicking. This will help you stay fresh in your pain cave, where training sessions can get warm because of the lack of air movement.

If you have a fan to hand, the Lycra®, combined with loose mesh side panels that maximise ventilation, will ensure your sweat evaporates fast and lowers your body temperature, to let you ride to the extent of your capabilities.

The shorts have raw-cut leg ending to keep the legs securely in place, whilst feeling weightless on the skin, while the Progetto X² Air seat pad is known for its luxurious feel over the course of a long training session.

This combination of all-day comfort, a great fit and superior moisture control ensures that the Insider Shorts can't be beaten when it comes to making you feel and function at your best in your home gym.
