Thanks to its long and narrow shape, the Fly High Pro X Series Tube Sac is perfect for adding that extra bit of hidden ballast.


The Fly High Pro X Series Tube Sac is the perfect shape for ski locker found in the floor of most boat. It's longer 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.

Fly High FATSAC Updated Look

New Look, Same Original FATSAC

The same ballast bag you’ve grown to count on but an updated, much improved look. The all-new FATSAC looks good and performs great. A new feature is the additional 4th port at the bottom for added versatility.

Fly High Pro X Tsunami Pump

Fly High Pro X Tsunami Pump

Using the Fly High Pro X Tsunami Pump, your Fly High FATSAC ballast bags will fill/drain at a whopping 1200 GPH. That is over 165 lbs. per minute! Spend less time waiting and more time riding thanks to this pump.

    Fits Perfectly
    Nathan Green

    Fits perfectly in my 03 malibu ski locker and replaced the beat up original. Excellent choice for this area in any boat

    Perfect Fit!
    Marc Saxton

    Put this tube sac under the observer seat in my 2011 23LSV to boost my surf wave. Couldn't be happier with the quality and fit!

    Excellent value and works great!
    Mark Hall

    Purchased to replace the sad excuse for ballast bag in the center ballast of our X-30... that actually burst!

    Not gonna worry about this one bursting! Made tough and to last!

    WakeMAKERS has it going on! This was our second order and there will be more to come!

    Best "bang for your buck"!
    Kendall Hedges

    I purchased three of these for my 97 Mastercraft Prostar 190. They're the perfect size to add weight just where you need it!

    03' MC X-2
    Brandon Dimicelli

    Perfect replacement for canter locker ballast in my 03' MasterCraft X-2. I was able to use the existing ballast hoses from the original ballast bag that had cracked. Easy 10 min install using Flow Rite quick release connectors.

    210 Super air nautique

    This is an additional one that I bought and it works perfect. Wake makers did a great job at recommending the best set up for my boat. Thank you

    Perfect fit under the rear seats in Super Air Nautiques

    The Fly High Tube sac is a pefect fit under the rear seats in 07 and newer Super Air Nautiques. I put one on each side under the seats in my SAN 220. If you slide it all the way forward it will go about half way up the slope on the wedge tanks on the 220s. Because of this I would reccommend getting enough hose to put in the fittings in the front. If you put them in the back it will create an air pocket when the bag is about half empty and will not drain all the way, assuming you are plumming it into the factory ballast.

    Perfect fit in Yamaha AR210
    Sean Adams

    This ballast fit perfectly in the aft storage area made a huge difference when surfing behind my jet boat. Yes you can surf behind it without a rope!

    Thanks wakemakers!

    This missing link!

    I dropped this whopper under the back deck on my Team Air Nautique 216 and now the surf wave and wake rock. It was the missing link, I've used other sacks which take up more room and provide less weight. Great price and clean look.

    Perfect for center ski locker
    New 2 Texas

    Have this tucked under the floor inside the center ski locker of my 1996 Sunsetter LX. a nice easy way to add a couple hundred pounds of weight without breaking the budget. I am about to purchase some more equipment and automate the sack so i don't even need to open the hatch to fill and drain. awesome product and great price.

    Final sack to my built in system

    Been looking for a ski locker sack to finish my custom built in ballast set up in my 92 MC prostar 205. I have the rear seat bottom sack that i installed last summer from wake makers. Now i cant wait to install this tube sack in my ski locker so one flip of a switch and everything fills. Thanks for all the great help. I will post pictures on face book some time of my custom install i did.

    perfect fit for my ski locker

    I bought this to put in my ski locker, 1994 mastercraft maristar 225 vrs, I previously had 2 v drive sacs in back and 2 tube sacs under the front seat cushions, this sac fits perfect in the ski locker, I can still keep a ski in there when it is not full if I have to. Wake makers normal high quality and fast service is great and they are very helpful.

    perfect for ski locker

    This bag fits perfect in the ski locker of my 2000 Moomba Kamberra, still allowing 3-4 ski's to fit on top of it, even when full! Not the heaviest bag, but convenience plays a part in happiness too. VERY well built products. Plan on purchasing more real soon.

    Love the Red color

    I have a malibu with the darker red color. This bag is really close to matching the color of the boat. Even though you do not really see the bag all that often in the ski locker, however its better then boring old gray. It also fit perfect in my 05 malibu sunsetter lxi and helped shape the wake even more.

    Love it!

    I've had a cheaper fats sac and pump that I had bought off ebay the connection would leak and pop off and it wasn't long before the seals were busting and leaking around the fill spouts without even over filling, then I used my buddies Fly hi sac an Tsunami pump and felll in love with the ease of the connection and how quickly they filled and empty the material itself is just way thicker and more durable I guess you get wht you pay for as for my old sack it was picked up by the garbage man friday as for my two fly hi sacks they are currently makin my glastron a wake machine and am currently getting ready to purchase the cube to offset the drivers weight!
