Designed as the perfect layering piece, wear Cronos under a soft-shell or wear it on its own. Specifically designed to keep you comfortable in a wide range of activities, our raised grid-fleece allows airflow to pass through the fabric during high energy motion while the tricot-brush back retains warmth during stationary times. Cronos is surprisingly breathable for a fleece layer, meaning you'll never want to be in the field without this hoodie.
