KastKing KastPro Braided Fishing Line - Spectra Super Line - Made in The USA - Zero Stretch Braid - Thin Diameter - On Biodegradable BioSpool! - Aggressive Weave - Incredible Abrasion Resistance! MADE IN USA - KastPro 4 carrier Spectra braid fishing line is proudly manufactured in the USA in our ISO 9001 and Aerospace AS 9100 certified facility to ensure the highest quality possible. Tested and approved by Bassmaster Elite anglers, professional fishing guides, charter boat captains, and select Team KastKing Pro Staff members. AGGRESSIVE DIAMOND WEAVE  Thin but exceptional strong Diamond Weave is incredibly tough and abrasion resistant. It is the perfect braid for the toughest fishing conditions such as heavy cover, vegetation, rocks, and underwater wood structure, outperforming any 8 strands braided line on the market. SPECIAL COATING - KastPro is coated to be color fast and has better abrasion resistance. Other brands use a water based coating which tends to merely rest on the surface of braid line and is naturally repelled by the braid material. This results in color fading and reduced abrasion resistance over time. The KastPro process uses a bio solvent based coating that penetrates and wicks into the braid for a more uniform coating with better color, coating life, and increased abrasion resistance. GREAT CASTABILITY  KastPro Spectra braids round, smooth finish delivers long, easy casts for both freshwater and saltwater fishing. It leads the industry with the thinnest possible diameters per rated breaking strength in a 4-strand braided fishing line. Low stretch properties means faster hook sets and greater sensitivity. BIOSPOOL As an extra benefit to our environment, KastKing KastPro fishing lines are spooled on our KastKing BioSpools, which are made with wheat straw. Unlike plastic spools, BioSpool will decompose naturally to reduce landfill bulk.KastKing is an ICAST award-winning manufacturer.
