The HO System Vest is a 4-panel, super comfortable and stylish life vest that's great to take anywhere and everywhere. Increased arm holes and segmented foam and rib panels give the System more mobility than other vests. The dual-hinge front provides increased mobility, range of motion, and comfort. A 3-dimensional cut provides a sleek performance-based fit, while the dual Tru-Fit flex panels give you the ultimate adjustability and comfort to fit your specific body contours. With superior drainability, the System quickly releases water to keep the skier lighter and drier. Lastly, the oversized armholes and front zip entry allow for maximum maneuverability and reach and easy entry.• Coast Guard approved• Men's Chest Sizes: S(32"-36"), M(36"-40"), L(40"-44"), XL(44"-48"), 2XL(48"-52") Dual-hinge front for increased range of motion and comfort Superior drainability keeps the skier lighter and drier USCG approved | Men's System CGA Life Vest size XL
