The Full Throttle teen nylon life jacket is designed with a deep neckline for a more comfortable fit and the large armholes allow for better mobility on the water. The vest fits teen and young adults weighing over 90 lbs. and is styled to provide a better fit for teens transitioning from the youth to adult sized life jackets. The adjustable belts and chest strap keep the vest in place and prevents ride-up or shifting. This U.S. Coast Guard and Transport Canada vest is great for skiing, boating, fishing, or just relaxing on the water.
