The Stahlstern is built on the evolved MILLE GT C2 EVO platform. We opened the front of the collar and updated the fit across the chest and throat, relieving pressure for easier breathing and less restriction. The sleeves and collar feature a new material that’s almost 30% lighter than the previous jersey’s sleeve material while retaining the highly elastic, wrapping fit and active moisture-management. The new bonded hem and zipper reduce friction between layers and rippling across the stomach while in the riding position.
