Whether its 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 Open Bow Triangle is designed to fit in any open bow boat application. It accomplishes this by conforming to fit the space. When fully inflated it adds up to 650 lbs. of ballast. Each Open Bow sac comes with all the fittings youd need to use with our Supa pump(pump sold separately). We also now offer custom printing so you can have virtually any design you want on your sacs.
