Whether it’s world class athletes like Noah Flegel and Bec Gange, or world class boat manufacturers like Nautique, Moomba/Supra, and Malibu/Axis; they all trust FatSac for their ballast needs. When you need to perfect your wave for wakesurfing, hyrdrofoiling, or wakeboarding you need a FatSac ballast bag. Each FatSac ballast bag is hand made in USA to the highest quality and durability standards. We also make all our own fittings in house so we can fully customize any setup to get you dialed in.

The Fat Sac is one of the flagships of our stock lineup. At 50X20X20 it fits in quite a few different places and adds 750 lbs. of weight. Each Fat Sac comes with all the fittings you’d need to use with our Supa pump (pump sold separately).
