Shield yourself with the Patagonia Men's R4 Insulated Jacket. It protects and warms with a Polartec® Windbloc® laminate, sandwiched between a low-nap polyester microfleece face and a high/low R1® (Polartec Power Dry®) grid polyester interior used throughout. The sonic-welding and micro-stitch technology on the zipper seams greatly reduces bulk, making the jacket incredibly supple and with a sleek appearance. Microfleece lines the collar, cuffs and hem, and seamless shoulders allow pack-wearing comfort. It features three external zippered pockets.
