The Upgrade X4 is a braid made from high-density polyethylene (0.98) designed for lure fishing with a retrieve technique. It stands out for its high abrasion resistance as well as excellent linear strength. The Upgrade X4 benefits from WX braiding technology (cross-fibre braiding) as well as 2 coating treatments that significantly improve its characteristics. Ideal for baitcasting fishing as well as all approaches where fishing spots are cluttered and the risk of friction is high, this braid features alternating colours with a pink marking 15 cm long every metre, which helps "break" the visual perception of a white line underwater and makes it easier to see above water.
