Castelli's pro riders know the importance of the right base layer for the conditions, which is why they wear the Team Sky Pro Mesh Short-Sleeve Base Layer under their jersey when temperatures are less than ideal. The Pro Mesh is made for the widest range of conditions compared to Castelli's other base layers, keeping you dry in temperatures ranging from cool to mild. It's constructed from a 3D mesh fabric that provides excellent moisture management, and features a lie-flat waist hem that tucks neatly and comfortably into your shorts. Sublimated print graphics let you show some style when you open up your jersey zip.
