Straightline Sumo ballast bags add movable weight where the boat needs it, with heavy-duty construction and high-flow fittings designed for repeated filling and draining. Choose the shape and capacity that fits the space — the point is useful, controllable ballast without turning the boat into a permanent plumbing project.

• Sumo Skin 1000D material — heavy-duty construction designed for constant filling, draining and compression.
• Fully welded seams — eliminates stitched seams that can leak or separate under pressure.
• Fast Sumo Link fitting — connects to Sumo pumps for quick filling and draining.
• 450lb size: 102 x 40 x 40.
