FleeceWool Polo is a warm and comfortable high-neck zippered shirt designed for hiking, skiing and outdoor activities in cold weather. The high neck with zipper gives you the flexibility to adjust the temperature as needed, whether you need extra warmth or quick ventilation. The thumb holes ensure good wrist warmth and that the sleeves fit well in use. FleeceWool is a uniquely developed wool fleece that combines the classic fleece feel with the superior properties of merino wool. FleeceWool is made from 93% merino wool and has a soft and brushed inside that creates small air pockets. These provide superb warmth and insulation without feeling heavy. FleeceWool is our most insulating material. It's a year-round favorite that works just as well as an insulating midlayer on cold days as it does for relaxing in the cabin.
