The technically advanced Castelli Alpha Jacket protects you from the wind and rain. Made from Gore®Windstopper® 150 fabric, the jacket is windproof and water-resistant, with four way stretch fabric for increased freedom of movement. Designed to keep you warm with just a base layer on underneath, the Alpha jacket features a full front zip that can be opened to provide ventilation at the top of your chest.

The insulation layer is detached from the windproof layer so the windproof layer can be opened for breathability while also enabling moisture to be evaporated. New fabric around the waist will lie completely flat for optimal aerodynamic performance and when in the riding position it conforms to your body to prevent billowing.

The wrists of the jacket feature flat raw-edge construction to fit perfectly into your gloves to keep cold air out and to increase comfort. Complete with a collar that follows the bends of your neck, a front zipped pocket, three rear pockets and a zipped rear pocket with reflective detail for improved visibility.
