The Assos elementZero Vest insulates your core and shelters you from the wind. The back of the vest extends over your bum to protect you from road spray, but flips up when you prefer not to sport the "duck tail" look. A ventilation system in the back provides much-needed breathability so you don't overheat. Zipper garages at the top and bottom of the front zipper protect your chin and your shorts from being snagged by the zip pull, and reflective stripes boost visibility.
