Product Description
Trusted by world-class athletes and leading boat manufacturers, FatSac ballast bags are engineered to help you dial in the perfect wake for wakesurfing, wakeboarding, and hydrofoiling. The FatSac W704 Pro X Series Tube Sac delivers 370 pounds of ballast in a slim, versatile shape designed to fit v-drive compartments or above-deck storage areas.
Handmade in the USA, this Tube Sac is constructed from FatSac’s proprietary layered vinyl, purpose-built for ballast use and UV stabilized for long-term durability. Welded seams are reinforced with tape to provide industry-leading strength you can rely on season after season.
Equipped with four ports and all required fittings for use with the Supa Tsunami Pump (sold separately), the W704 offers flexible plumbing options and easy integration into custom ballast systems. Custom printing is also available, allowing you to personalize your setup with virtually any design.
