Last year's version of this garment was called the Gabba Long Sleeve Jacket, but with Winter 2016 Castelli are reserving the Gabba name for the original Gabba short sleeve jersey. So many people called the long sleeve version of the Gabba “perfect,” so naturally they've renamed it the Perfetto Jersey and set about improving on perfection. With an improved water-repellent finish it will keep you drier without affecting breathability. The cut has also been further refined so it fits better than ever. Laser cut the drain holes in the pockets makes for a clean sleek look while a totally redesigned splash flap on the back means it lies flatter and fits better. The reflective logo back there keeps you visible.
