Yasi development team spent many years of researching, studying and testing in collaboration with the best Japanese manufacturers to develop superior braided line using the newest technologies that gives anglers the confidence in any fish-fight. The fiber twist formula used in our line is a new technology that gives the braid an outstanding anti-abrasion to give it higher rock friction resistance during bottom jigging.The silky coating layer protects the line to give it a super smooth movement and durability that makes it extremely sensitive to any bite. Moreover, it adds tension without any stiffness that reduces the tendency to cling to the rod guides.As part of our social responsibilities, Yasi is using 100% natural pigment in the line coloring to avoid any pollution to our beloved sea environment.
