The Castelli Perfetto Long Sleeve Jersey is a reworking of the Gabba Long Sleeve. Its essentially the same item although the fabric is a bit more breathable and a little better at shedding rain and the pockets have new drainage holes –it also manages to improve the much loved spray flap over your bum while adding a few extra colours and some additional visual notes.Castelli Cycling on the Perfetto LS: "Its hard improving on perfection; Last year’s version of this jacket was called the Gabba Long Sleeve Jacket, but with Winter 2016 we’re going back to reserving the Gabba name for the original Gabba short sleeve jersey/ jacket. We kept hearing so many people call the long-sleeve version of the Gabba as “perfect,” so we’ve renamed it the Perfetto Jacket and set about improving on perfection. We’ve improved the water-repellent finish so it will keep you drier without affecting breathability. We’ve refined the fit. We’ve laser cut the drain holes in the pockets. And we’ve totally redone the splash flap on the back to make it lie flatter and fit better. The reflective logo back there keeps you visible."
