The Castelli Gabba RoS W is a new women's cycling jersey that changes cycling in colder and wetter conditions for the better. For this fourth-generation Gabba, Castelli started with a clean slate and made significant changes. The newly developed GORE-TEX INFINIUM fabric is virtually waterproof, greatly improving the jersey's water protection. The fabric is lightly brushed and made to be warmer at the front. The fabrics at the back are lighter and more water-resistant as well as highly stretchy and breathable. The Castelli Gabba RoS W features taped shoulder seams and a YKK Vislon zip with a flap for even better protection against rain and wind. Based on several tests carried out by pro team INEOS Grenadiers, it was decided to add 2 larger back pockets which are easily accessed with cycling gloves on. There is no back pocket with a zip on this shirt, which means your belongings cannot be stored extra securely. But there is a dedicated bike pump sleeve in one of the back pockets. The droptail design of the Gabba's back panel includes a large black reflective panel for enhanced visibility. So with the Castelli Gabba RoS W cycling jersey, you are not only better protected from water and wind but are also extra safe on your bike.
