The Fly High Fat Sac EXV comes with dual drain ports for better integration options. The Fat Sac weighs 750 lbs. and is 50 inches x 20 inches x 20 inches. This will fill the entire locker space in most V-Drive Wakeboard Boats.


The W707-EXV has been discontinued now that the W707 Fat sac comes standard with the additional drain port.

This EXV Fat Sac has been standards of weighting a wakeboard boat. The W707-EXV is the same size as the standard W707 but includes an extra drain port on the back panel. This makes integration with 2013+ Malibu and Axis boats plug and play possible and also allows the use of an X-Link ballast transfer system.

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 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 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.

    Fits nicely in the Malibu 22 MXZ Locker

    This bag fit nicely in the locker on my 2012 Malibu 22MXZ. I did add the recommended reinforcement to engine divider panel "Engine Divider Panel Saver". Easy to install.
