The most popular wakeboard ballast bag of all time, period.

There's a reason the Fly High Pro X Series Fat Sac wakeboard ballast bag is continually one of our best selling products; it offers a huge amount of weight for a great price, in a very versatile size. Looking for a better surf wake from your direct drive or v-drive boat? Want a better wakeboard wake or need more weight in the front of the boat? The Fat Sac works in almost any common location for nearly every application, which means chances are, it's the ballast bag you've been looking for.

The Fly High Pro X Series Fat Sac Ballast Bag is the original ballast bag that redefined new standards of weighting a wakeboard boat. The versatility of its size is the secret to the Fat Sac's success, it's the sweet spot for volume versus weight, which means it will fit in almost any boat, and offer a huge increase in wake size.

Common Applications

V-Drive Boats: Place the Fat Sac in the rear lockers next to the engine on 20-25' v-drive boats for use when surfing or wakeboarding.

Direct Drive Boats: Place the fly high 750 on each side of the engine compartment for an additional 1500 pounds of pure wake enhancement that is perfectly balanced. Configure those same bags in an "L" shape next to and behind the engine compartment for surfing bliss.

Other Applications: Use the Fat Sac anywhere it will fit dimensionally that you need additional weight; it works well in the open bow walkway, on the floor or up in the bow on top of the seat cushions.

Fly High Pro X Series wakeboard ballast bags were the first products designed from the ground up to be used in a wakeboard boat. Starting with a blank canvas, Fly High was able to rethink nearly every aspect of wakeboard ballast bag constructions and functionality. Gone are the day of two part construction, leaky waterbed connections, and fittings that are difficult to connect. By building their wakeboard ballast bags from a single layer of durable yet flexible vinyl, the same material that is used to build white water rafts, Fly High is able to offer unmatched strength and durability in an easy to use package.

Additionally, Fly High Pro X Series ballast bags feature multiple threaded ports that are built into the construction of the bag. Unlike the blue waterbed connections use on other brands, these strong ports feature durable threads and can be used with Fly High’s options fittings for compatibility with nearly any wakeboard ballast system you can imagine. Step up to the Fly High Pro X Series wakeboard ballast bags and experience the most convenient, durable and highest performing ballast bags on the market.

    750 lb fat sac

    Overall a great bag that does what it says. Only thing is that in the picture it appears to have a rectangle shape but in reality it is more like a blob on the floor of your boat.

    Worth every penny

    Works great, durable, and the black bags look great in the rear compartment.

    The ballast bag

    When you think of ballast bags, you think of the Fly High 750 first. Best quality, function, and looks. Cant be beat.

    Quality no leaks

    Much better construction than my OEM mastercraft bags on a 2003 which leaked around the intakes. Think this is going to last a good 10 years longer and work much better thx!

    Couldn't be happier

    I added two of these to my 1998 Ski Challenger per the suggestion of tech/sales support. Quick setup and great wake. Before and after video link.
