Note: Castelli size their clothing small. For the best fit, go up one size
At the waist Castelli have a new fabric and construction that lies completely flat and is streamlined for aerodynamics, yet when you drop into the riding position it follows your body without binding or billowing. At the wrists the Alpha has a new flat raw-edge construction that interfaces perfectly with Castelli's gloves to keep drafts out and improve comfort. At the collar Castelli have a new articulated construction that follows the angle of your neck whether you're standing or riding in the lowest aero position. With the latest fabrics Castelli can essentially build a winter jacket that will keep you warm in all but the most extreme conditions with just a base layer underneath. Riding in these pieces shows how effective they are at regulating temperature and comfort while helping to keep you drier.
