Make not having the right winter clothing an excuse of the past with the Castelli Alpha Womens Jacket. Totally windproof and water resistant with an ergonomic four-way stretch thanks to the Windstopper 150 fabric, the Alpha Jacket offers the perfect level of protection for the entirety of your cold winter ride.

Castelli Alpha Womens Jacket

With the Castelli Alpha Womens Jacket winter miles don't seem so bad, in fact, they feel great. The storied Italian manufacturer has gone back to the drawing board with the Alpha jacket to create something truly special that is built to perform.

Windstopper 150 fabric is integral to this top-tier level of performance. The fabric provides complete wind protection and water resistance with a four-way ergonomic fit that ensures freedom of movement without any irritating flapping or baggy areas.

The Alpha construction is a total rethinking of the winter jacket with a separation of the windproof and insulating layers on the front of the jacket. This separation gives you far more control over ventilation and as a result, when you are working hard, you can simply open the external zip to allow airflow to dry the thermal layer and keep you cool without allowing you to get cold.

Further protecting you from wind penetration, the offset asymmetric YKK Vislon zipper prevents any wind from getting to your core and lies flat for optimised aerodynamics.

Another combination of aerodynamic performance and comfort comes in the form of the raw-edge waistband and wrist-cuffs. Both of which lie completely flat to the skin to seal you off completely from the wind and sit comfortably no matter what your riding position is.

The high articulated collar provides a similar level of comfort by sealing you in from the cold while at the same time providing soft comfort whether in the riding position or standing.

Three rear pockets are complemented by both a zippered front pocket and a zippered rear pocket so you are sure to always have enough room for your riding essentials and valuables.

Available in several dynamic and head-turning colour schemes, the Castelli Alpha Womens Jacket looks fantastic as part of any riding outfit and the added reflective detailing further aids your visibility to others on the road.
