The Divide is one of our lightest and most easily packable jackets (only 125 grams in a size medium), developed for unexpected changes in weather or chilly mountain descents. MicroTek Supreme™ fabric across the front,  shoulder panels and arms is exceptionally good at blocking wind chill. Zero-Weight mesh in the side panels, arm insets and back offers excellent stretch and breathability during periods of increased effort. A two-way YKK zipper (with reflective taping down both sides of the teeth) makes for easy access to pockets at a stop or when riding. The packability of the Divide Vest is one of its highlights. Roll, scrunch or fold it into one of the rear pockets of your Jersey and you will still have room left to store other items for your all day adventure.
