SUMO MAX 850

850 LBS - 50" 20" 20" 1× MAX FLOW LINK 4× 1" NPT

SUMO SKIN 1000D:

SUMO Sacs are made with our own flexible and puncture-resistant fabric, “SUMO Skin.” It has a durable 1000D polyester core that is heat laminated to lightweight plastic film skins with a bonding agent. This sandwich construction is 150% stronger in tearing tests and 37% higher in tensile strength than our competitors, making it the most durable ballast bag available.

SUMO SEAMS:

Every SUMO sac is double welded to ensure a watertight seal. Our 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.
