This jacket was initially created as a long sleeve version of the Gabba -- kind of a cold weather version of the Gabba. But we kept hearing so many people refer to the long-sleeve version of the Gabba as “perfect,” so we’ve renamed it the Perfetto Long Sleeve. It's a great piece in cool conditions with just a light base layer, or it goes to very cold conditions if you add an extra layer or 2 or 3. 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.
