Berkley Fireline Fishing Line is the best braided superline for spinning reels, where incredible strength, thin diameter, toughness and sensitivity are important. Also effective for baitcast reel applications. Improved thermally fused Fireline is smoother than ever-right out of the package. INCREDIBLY STONG; three times stronger then mono. TOUGH AND ABRASIION RESISTANT; slices through vegetation. INCREDIBLE SENSITIVITY; telegraphic feel for structure and strikes. LONG AND FAST CASTING; better then ever before.
