Castelli have re-engineered the cycling jacket in Alpha series and as a result they have created one of the best jackets currently on the market. The name Alpha denotes the first in a series of new products that Castelli are introducing that feature new techniques and fabrics so give you the ideal cool and cold weather jacket.

Castelli have focused on two perennial problems with cycling jackets and jerseys. Firstly ventilation. With Alpha, Castelli have detached the insulating layer from the windproof layer so that you can open the windproof layer to let air in to ventilate and help evaporate moisture. This is very effective at regulating temperature and comfort while helping keep you drier as you build up a sweat. The second area Castelli have focused on are the openings. At the waist a new fabric and construction allows the jersey to lay completely flat for a streamlined, aerodynamic fit. Dropping in to your riding position the fit follows your body position without binding or billowing. This same construction at the wrists ensures a perfect fit with your gloves.

The Alpha jacket comes packed with many great features including an asymmetric external YKK Vislon zipper, silicone text gripper at the waist to keep the jacket from riding up and back ventilation to give you a constant airflow. The jacket is finished with multiple pockets including three rear pockets for storing all your ride essentials and zippered rear pocket with reflective webbing for storing any valuables.

Note: Castelli clothing is sized small, Tweeks Cycles recommend you select one size above normal for an athletic fit, or two sizes above if you prefer a more relaxed fit.
