Built to withstand the test of time and enhance every performance, the Formation 3L Jacket is a seasonal staple. Made responsibly from a PFA-free four-way stretch nylon shell with a permanent GTT Empel treatment, for enhanced water resistance. This high-performance jacket features a next-level Trizar® heat re-radiating technology throughout that provides excellent thermoregulation for both summer and winter wear, a helmet-compatible hood for extra coverage, and a Recco® reflector for an additional level of safety. It's finished with various YKK® zippered pockets that give plenty of space for keeping all valuables safe on the go, as well as featuring an innovatively designed YKK® Touchlink™ center front zipper that's powered by the Lifekey™software platform, a new technology that allows its user to track, manage and view their activities from their smartphone.
