No-sweat wear comfort on demanding trails: The PERFORMANCE fleece jacket gives you the insulation performance you would expect from a 100 weight fleece - and the wear comfort is exceptional. This is because it is made from NANUK 100 ATHLETIC Q.M.C., a fleece fabric that was specifically developed to deliver high-end functionality. It absorbs moisture directly from the skin and dries quickly. So you’re left feeling nice and dry even during the toughest sections of the route. Factor in the light weight and you get the perfect fleece jacket for ambitious hiking trips.
