AEW070 is a sleek, beautifully tailored insulation piece designed without compromise. The pure wool outer is from Portugal and has been Teflon treated to protect the PrimaLoft® Gold insulation down blend. For the upper we selected waxed cotton with a waterproof lamination. We used Pertex® Microlight ECO lining throughout and created a soft merino ribbing to seal in the warmth at the cuff and hem.
