Packed with Hydrodown®, this jacket might be light but it still operates at a proper heavy level. Downpours can do one. Still, we can’t take all the credit. Our nifty body mapping traps pockets of warm air and through our special lining, bounces your body heat back at you so you stay warm (thanks for the assist). Wind picking up? Our Pertex® Quantum outer is the perfect lightweight shield to have that breeze slip right off you. Well, we couldn’t let you do all the work could we?
