FatSac W703-GRAY Fly High Pro X Series Side Sacs Gray, Pair 260 Lbs. Each

The FatSac Fly High Pro X Series Side Sacs (W703-GRAY) are a pair of high-capacity wakeboard ballast bags purpose-built to add serious weight in tight, narrow spaces aboard inboard and open bow boats. Each sac holds 260 lbs. of ballast (520 lbs. total per pair) and measures a slim 48" x 12" x 12", allowing them to slip along the side of the engine compartment, under seats, or into compact storage areas where bulkier bags simply won't fit.

Key Features:

• Slim, versatile profile — fits along engine compartment sides on direct drive inboard boats and conforms to fit under seats or in compact storage compartments
• 260 lbs. per sac / 520 lbs. total — adds significant, centered ballast to balance weight aft of the engine for improved wake shape
• 3-layer Valmex material construction — the same tough material used in river rafts and inflatable boats, delivering outstanding puncture and abrasion resistance
• Welded and taped seams — extra-wide seams are both welded and taped for maximum leak protection, a step other ballast brands skip
• 2 fill/vent ports and 1 drain port per sac for easy filling and draining
• Handmade in Milwaukee, Wisconsin, USA with strict quality control standards
• Includes a 1-year warranty
• Sold as a pair — gray colorway, no color surcharge or shipping delay

FatSac Pro X Series ballast bags are trusted by leading boat manufacturers as OEM equipment and are the original choice for wakeboarding and wakesurfing enthusiasts. Whether you're chasing a bigger surf wake or a cleaner wakeboard wake, the W703-GRAY Side Sacs deliver maximum ballast in a form factor that fits where other bags can't.
