Some days you look out the window and the clouds in the sky look ominous, but you just want to ride. The Tempesta Lite is the jacket to throw in your pocket when you head out the door. It's extremely light so you'll hardly notice it's in your pocket, and it packs down so small (about half a pocket) that you won't sacrifice any storage space if you want to bring it with you "just in case." The fabric is waterproof so you'll stay dry if those clouds do decide to open up, but it's breathable too, to keep you from getting wet from the inside. It's also the perfect piece to put on for those long descents when you want to keep the wind off your chest and arms.
