They took the durability of the favorite Flylow Quantum Jacket and added a just-right layer of recycled micropuff insulation. The result is the Flylow Vector Jacket, a hardshell armor of a coat that can handle a beating through the trees and is built warm for colder days, eliminating the need for bulky midlayers. Waterproof zippers and two-layer Surface fabric make it stormproof on the snowiest of days.
