Our Men's Smartloft 120 Jacket features performance up front and breathability in the back. The front of this midlayer jacket uses our 120g proprietary 50% recycled wool insulation, giving you breathable, lightweight, packable warmth. The back panel is made of our Sport Fleece fabric with a DWR weather protection finish—perfect for high-intensity workouts. Two zippered hand pockets and one zippered chest pocket with a media cord outlet means you can stow your keys and phone without worrying about them falling out. With Merino lining to help ensure you're comfortable from the inside out, this men's jacket is the only thing that might work harder than you do.
