The original Fly High fat sac ballast bag redefined and set new standards. These sacs are the most demanded sacs on the market for their durability and ease of use. Two of these on either side of the engine will add 1500 lbs. of ballast when full. The perfect ballast bag for wakesurfing becasue it will fit beside the engine compartment on direct drives and in the locker of v drive boats.

  • Integrated Design: The long narrow shape of the Tube Sac makes it ideal for placement in the unused storage lockers found in most wakeboard boats.
  • Quick Connect System: Forget about blue waterbed fittings that leak and are hard to connect, this is the future.
  • Dense Plastic Threaded Fittings: The threads in these bags will never fail and are guaranteed not to leak thanks to an integrated O-ring seal.
  • Valmex Material: One single layer of tough material makes punctures and abrasions a thing of the past. This rugged material is also anti-bacterial to reduce mold growth.
  • Welded and Taped Seams: The seams on these bags will never fail and are guaranteed not to leak.
  • Single Layer Construction: Forget about inner liners and outer covers and no longer search for an inner bladder valve, just connect, pump and go.
