For anyone looking for more freedom of movement while keeping their core warm on brisk days, the new Flight Outfitters Airfoil Vest delivers. Based on the pilot-tested jacket, this rugged vest is a fantastic mid-layer between a long-sleeved base layer and an outer jacket. It offers the most versatility for colder days—stay warm during preflight with a jacket over the vest, then in-flight enjoy unrestricted movement with just the vest on. The Flight Outfitters unisex Airfoil vest is available in sizes small through XXL.
