  • Superior Tensile Strength – Built for extreme fishing conditions! KastKing Extremus braided fishing line is an incredibly strong braid line with 4 strands of MultiTuf fibers giving you ultimate confidence in fresh water and saltwater fishing conditions. Greater knot strength is an added bonus. Exceed your limits; take fishing to the next level with Extremus.
  • Unique Coating – Unlike other braid line brands using water-based dyes that wear off easily and allow water to penetrate the fibers, Extremus braided line utilizes an “petroleum derivative” based coating that is the best at preventing water absorption and color fading.
  • Advanced Braid Technology - Combining proprietary KastKing processes of “Diamond Weave” technology, Extremus braided fishing line is extremely abrasion resistant and made for fishing around hard structure.
  • Thin Diameter and Extreme Sensitivity – KastKing Extremus braided line is available in consistent line strengths from 6-80 lbs, but with the monofilament diameter equivalent of lines from 1-20 lbs. Extremus braided fishing lines are also zero memory, zero stretch and extremely sensitive. You can cast farther, feel the slightest bites even with heavier lines and have the confidence to land any large fish in rugged conditions.
  • BioSpool – As an extra benefit to our environment, KastKing Extremus fishing lines are spooled on our KastKing BioSpools, which are made with biodegradable wheat straw. Unlike plastic spools, BioSpool will decompose naturally to reduce landfill bulk.
