The Origami Lift Bag got its name because of the unique nature with which it is designed. Using a continuous panel of 24oz. Canvas, The Last U.S. Bag Co. folds this and sews it together to eliminate any seams with direct exposure to compromise. True supported sling design means the payload is supported from underneath, with 8 legs of webbing sling to balance the load. Forged steel loops for rigging and Vinyl dry-tight closure for safe lifting and protection of payload. HD 32oz Vinyl capped bottom for protection against the elements while on the ground and increased abrasion resistance.
