FleeceWool Longs is a warm, close-fitting and comfortable wool longs, designed for cold winter days, outdoor life and relaxation. The snug fit makes it ideal as a baselayer under shell pants on a hike or as an extra warm longs for everyday wear. 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.
