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.
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.
