EXTREMELY LIGHTWEIGHT AND COMPACT. When the weather gets nasty in the middle of your ride, reach into your jerseys back pocket and pull out the Leggero. With its close to body fit, this jacket wont flap in the wind. Naturally, its windproof, but it is also water resistant while maintaining reasonable breathability, in part thanks to the expansion vent in the back.A double pull zipper will add extra temperature regulation. The Leggero is so light that it comes with its own stuff sack, so its as easy to take with you as an energy bar. The mesh lined collar wont chafe your neck when the jacket is zipped all the way up, and reflective tabs on the back keep you visible on early morning or late evening rides.
