Optimize your wave for wakesurfing, hydrofoiling, or wakeboarding with the FatSac Floor Sac ballast bag. Handmade in the USA to the highest standards, each FatSac is built for unmatched quality and durability. We craft our fittings in-house for complete setup customization, so you can create the perfect ballast system for your needs.

This Floor Sac model measures 42” x 40” x 13” and adds a substantial 800 lbs. of ballast weight, designed to fit almost any floor space in your boat. The sac’s flexible structure conforms naturally to available space, while its reinforced, UV-stabilized vinyl construction ensures it can withstand heavy use—you can even walk or step on it without worry. Each Floor Sac comes with all necessary fittings to pair with our Supa Pump (sold separately), making filling easy. Plus, FatSac offers custom printing options to add a unique design to your sac.
