Castelli AirCore Collection

There are moments in time where paradigm shifts are made. After 40 years of compromise, there is finally a fabric specifically engineered for the needs of cyclists, that delivers the breathability and air permeability required for higher intensity riding in changable conditions. Moreover, this fabric is light and stretchy; it is windproof and delivers sensible levels of water repelancy for almost all wet riding conditions - and it does it in a sustainable way. While historically these objectives were often diametrically opposed, Polartec's new AirCore is that shift - objectively better performance. No compromises. Environmentally sound.

Breathability as it should be.
