The KÜHL LOOKOUT™ features soft, smooth, and technical ELÜXUR™ fabric at the yoke, collar and cuffs for comfort and an 80/20 Cotton and Merion Wool blend at a 4.7 oz. / sq. yd. (160 GSM) fabric weight. Cotton is soft and breathes remarkably well. Merion wool is also soft and fantastic for temperature regulation. Inside the left front chest is a security pocket designed to keep your passport safe or cash and cards secure. The cuffs are adjustable at the wrist with two buttons. Kühl Signature metal buttons on the front. Two chest pockets. ELÜXUR™ fabric is easy care, wash and wear, soft to the touch, and fights odor with Ionik™ Technology: negatively charged silver ion threads in the fabric fight odor causing bacteria.
