For comfort as you climb, hike, or wander through wintry streets, put on the BlackYak Nelore Jacket before going out your door. This insulated jacket is filled with high-loft down for excellent warmth retention with a light weight. Fleece panels at the sides and under the arms ensure you get plenty of airflow without dumping all of your hard-earned body heat. The Nelore is built with Cordura Ripstop, so it stands up to the wear and tear of day-to-day adventures.
