The Women's Ascendor Light Pull-On is Rab's lightest fleece for mountain pursuits. Perfect for year-round ascents, the ultralight, stretchy fleece has a gridded lining to wick moisture and dry quickly if you work up a sweat. Rab alternated stripes of heavy and light fleece up and down the entire half-zip to increase breathable airflow. A slim fit lets you layer over baselayers and under shells while ensuring full mobility up and down the mountain.
