FatSac W704-GRAY Pro X Series Tube Sac Ballast Bag 370 lbs Gray 62x16x10

The FatSac W704-GRAY Pro X Series Tube Sac is a 370-pound ballast bag engineered for wakesurfing, wakeboarding, and hydrofoiling. Its long, narrow tube shape — 62" x 16" x 10" — makes it one of the most versatile ballast bags available, designed to slip into tight spaces where standard sacs simply won't fit.

Key Features:

• 370 lbs of ballast capacity in a slim 62" x 16" x 10" form factor
• Built from FatSac's proprietary Valmex layered vinyl — a material comparable to river rafting construction — for exceptional puncture and abrasion resistance
• UV stabilized for long-term outdoor and on-water durability
• Welded and seam-taped construction provides superior strength over season after season of use
• Four ports with all required fittings included for use with the FatSac Supa Tsunami Pump (pump sold separately)
• Compatible with FatSac's quick-connect valve system for fast fill and drain times
• Handmade in the USA at the Fly High facilities in Milwaukee
• Custom printing available (fees apply)
• Available in Gray (standard), Black, Blue, Red, White, and Camo

The W704's slim tube profile fits perfectly in ski lockers, v-drive compartments, bow walkways, under side seats, or on the floor forward of the engine compartment — making it one of FatSac's most popular and adaptable ballast solutions. The bag ships with all fittings needed for integration with the Supa Tsunami Pump system. Pump sold separately.
