The multi-purpose fiber that is ideal for rugged uses: sails, awnings, boat covers, and more. It is the most widely used fiber in the manufacturing of nautical ropes. Polyester is very durable and resistant to abrasions. The fiber is supple and dries rapidly, which makes it ideal for outdoor use. It is used in the manufacturing of moors, halyards, and spinnaker sheets. Its elasticity varies between 8 and 12%, depending on the braiding. This high degree of elasticity inspired Loftnets to develop an exclusive, less elastic material, the Marine 3S©.
