Built for proper rain rather than passing showers, the Nimbus Vest takes the aero silhouette of the Flight 3.0 and adds full waterproof protection. Taped seams and a waterproof YKK zip seal out the wet completely, while the lightweight Volare™ fabric moves with you and breathes when you're working hard. It packs down small enough to stuff in a pocket when the clouds clear. A reflective waist gripper holds everything in place and keeps you visible in fading light.
