Soft, castable and virtually invisible to fish, Seaguar's® high-performing INVIZX™ Fluorocarbon Fishing Line is ideal for both spinning and casting reels. Made from 100% Seguar resins, INVIZX is super strong yet sensitive enough to transfer light bites while offering advanced hook setting power and outstanding knot strength. INVIZX is also UV-resistant, abrasion-resistant, impervious to cold conditions and suitable for freshwater and saltwater. Spooled with Level Wind Technology™, Seaguar's exclusive design process that spools the line by laying it down on its side, never crossing for super smoothness without any line overstress or twist.
