The 48-liter yellow Optimist buoyancy bag is made from polyurethane-coated nylon, making it significantly lighter and stronger than PVC or PVC-coated bags. With a twist-lock tube valve for easy inflation and deflation, it ensures quick and efficient use. While it’s slightly heavier than the 43-liter version, the 48-liter bag provides better buoyancy after a capsize, reducing water intake in the boat. Be sure not to overinflate, as properly filled bags should feel soft. Over-inflation may lead to bursting in high heat. Avoid sharp objects in the boat that may puncture the bag.
