The secret to the Night Falcon jacket is a patented venting system on the front body; vertical zippers pull down a strip of outer Cordura, exposing perforated leather underneath. This allows cooling breezes inside, and enables the rider to modulate the degree of ventilation. There's also an air-induction system that channels cool air up the arms, and two exit vents control currents in the lower back, for an intake/exhaust effect and great climate control. All those entry points, however, make the jacket drafty when the sun goes down, so we'd add the compatible, insulated Streamliner Vest or the electrically heated Electron Vest to ward off cooler temperatures. The jacket has snaps to accept the vests and a zipper to fasten to many of Vanson's pants.
