+ Sumo Skin 1000D
Sumo Sacs are made with Liquid Force’s own flexible and puncture-resistant fabric “Sumo Skin.” 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 their competitors, making it the most durable ballast bag available.

+ Sumo Seams
Every Sumo sac is double welded to ensure a watertight seal. Liquid Force’s tough Sumo Skin is overlapped and hot air welded. 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.

+ Sumo Max Flow LINK™ Valve
Liquid Force’s new Sumo Max Flow valve is a new 1½ 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.

+ LINK™ Valve
Liquid Force’s unique LINK™ system provides a hassle free connection to your Sumo Pump, keeping your boat dry on the inside. The LINK™ Valve is watertight and can also be used as a convenient way to purge air from your bag.

+ 1” NPT Valves
New, easy turning cap with a perfect water tight seal. Pressure tested up to 6 PSI. Liquid Force’s 1” NPT ports allow built in ballast systems to fill, drain, and vent quickly for hassle free operation.
