Every Cocopani beach umbrella comes complete with the exclusive CocoSac, designed and developed by Cocopani. The CocoSac is a refillable sandbag that fits inside the umbrella carry bag in an easy to reach pocket. Once filled, it weights 13kg and attaches to the upper umbrella spokes, acting as a weight. Hence it keeps the umbrella stable in windy conditions and stops it flying away during strong wind gusts. This gives you total peace of mind when you’re at the beach. Also it has an easy clip on buckle with strap to attach the bag to the umbrella and matching print to complement your umbrella set.
