Our Ballast Jacket / Vest are purpose-built insulation pieces that are engineered to keep you warm when wet. Primaloft Black insulation offers the best in class warmth. A rugged exterior shell fabric offers professional-grade abrasion resistance, while the internal lining offers comfort. The Ballast is equally at home in the boat yard as it is in the bar. Hell, with the right girl, you could wear this out on a date.
