Lace up your running shoes and head out into the woods! This is where the Womens Arco comes into its own–a very light and breathable fleece pullover with excellent wicking performance that's ideal for use in a layering system. We made this pullover from a breathable, fast drying fleece fabric that provides basic thermal insulation. Wear it on its own in summer or as a Mid layer in winter for running, hiking, trekking or camping. The Womens Arco is a true all-rounder, suitable for all seasons and all activities.
