Thanks to the Fly High W704 Tube Sac long and narrow shape, this fat Sac is perfect for adding that extra 370lbs of hidden ballast.
The Fly High W704 Tube Sac is the perfect shape for the ski locker found in the floor of most boats. It’s long and narrow profile also make it incredibly versatile for use in other areas of the boat, such as the bow walk-way, or in storage compartments and under seats. There’s a reason this is one of our most popular bags; it’s incredibly versatile and will fit in a number of locations depending on where you need ballast.
Whether you need additional weight up front for wakeboarding or if you need additional ballast under seats in the midship for surfing, the Tube Sac is the perfect size to fit in most ski and wakeboard boats.
