When it comes to cold weather layering, an insulated vest can become your on-the-water best friend. The Grundéns Ballast Insulated 2.0 Zip Vest  retains your body heat with an 80G insulation value while also maintaining a high level of breathability and airflow for temperature regulation during a wide range of activity levels. Zippered hand-warming and chest storage pockets make this piece a fishing-functional must-have for cold weather, and durable water repellent treatments ensure that liquids and stains don’t penetrate the comfortable cotton-poly outer layer.
