The Castelli Insider 2 Bib Shorts are now lighter and cooler than ever to keep you comfortable during indoor training sessions.

The Lycra® that makes up the largest part of the shorts is extremely stretchy, ensuring a great fit, while also being breathable and moisture wicking. This will help to keep you 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 as fast as possible. This will lower your body temperature and let you cycle to the full extent of your capabilities.

The bib shorts have raw-cut leg endings that will keep the legs securely in place whilst feeling weightless on the skin, while the Progetto X² Air seat pad they're built around is known for its luxurious feel during long training sessions.

Meanwhile, the bib straps will hold the whole short up, allowing the waist to remain soft and un-elasticated, while adding little weight or airflow restriction, thanks their monofilament open knit construction. The combination of all-day comfort, a great fit and superior moisture control ensures that these bib shorts can't be beaten when it comes to making you feel and function at your best indoors.
