The Radical 2 Primaloft Women's Hooded Jacket is a puffy coat designed to keep you warm without limiting range of motion. There is 80 grams of Primaloft Silver Active synthetic insulation in the chest and a lighter weight 60 grams of insulation in the arms. This helps keep your core warm while limiting overlayering bulk on your arms. Dynastretch elastic fabric underneath the arms helps you feel uninhibited while moving outside in cold weather. This coat is a great option for staying toasty, but feeling free, while in cold weather.
