Castelli Alpha Jacket

Castelli Alpha Jacket

The name Alpha denotes the first in a series, and in the case of this jacket, your first choice. With the Alpha Jacket, Castelli introduces several new techniques and fabrics to construct cool and cold weather jackets. They have focused on two perennial problems with cycling jackets and wind jerseys.

First order of business is ventilation. With Castelli’s latest fabrics they can essentially build a winter jacket that will keep you warm in all but the most extreme conditions with just a base layer underneath. But when you open the front zipper you get a blast of cold air at the top of your chest, while the rest of your body remains too hot. The Alpha detaches the insulation layer from the windproof layer so that you can open the windproof layer to let air in to ventilate and help evaporate moisture. Riding these pieces shows how effective it is at regulating temperature and comfort while helping to keep you drier.

The second focus area is all the openings. At the waist, Castelli uses a new fabric and construction that lays completely flat, is streamlined for aerodynamics, yet when you drop into the riding position it follows your body without binding or billowing. At the wrists, Castelli's new flat raw-edge construction that interfaces perfectly with their gloves to keep drafts out and improve comfort. At the collar Castelli's new articulated construction that follows the bends in your neck whether you’re standing or riding in the lowest aero position.

Fit Notes:

1. On the bike, your Castelli jersey should
fit close to the skin.
2. Off the bike, your Castelli jersey might
feel tight across the chest and a little
short in front.
3. Castelli ProSecco treatment helps
perspiration evaporate quickly to keep
you cooler and drier.
4. Castelli jerseys are designed with the
sleeves articulated forward for maximum
aerodynamic performance.
5. Bibshorts should fit tightly enough
to support critical leg muscles through
compression without inhibiting
movement and constricting blood flow.
