Straight Line Sumo Max Ballast Bag - easy to use, durable and convenient for creating larger wakes so you can have more fun riding your massive new wake. Full range of sizes and weights available to tune your boat for the perfect wake shape.

Straight Line Sumo Max Ballast Bag 1000 holds 1000 LBS and measures 50"x 22"x 22". It has a durable 1000D polyester core that is heat laminated to lightweight PVC skins with a bonding agent. This sandwich construction is 150% stronger in tearing tests and 37% higher in tensile strength than the competitors, making it the most durable ballast bag available.

Every SUMO sac is double welded to ensure a watertight seal. You can see the smooth and clean seams on the outside of every bag, and a second welding operation applies an inch wide sealing tape to the inside of every seam.

The new SUMO MAX FLOW valve is a new 1 ½ Inch diameter high flow version of the Sumo LINK™ system. The SUMO Max Flow valve provides the same hassle free watertight connection to your Sumo Pump but with massive 50% LARGER intake. The Sumo Max system is 100% compatible with the classic Sumo and Big Bag ballast systems.
