Magnitude lines are ushering in a new era in fly line technology, headaches with clear lines are a thing of the past. Our new family is loaded with revolutionary new technologies making it most durable and slickest clear floating fly line on the market. Period.

Features -

  • Optimized for use above 50F/10C. This line can be fished below those temperatures, but will require stretching by hand to manage coils.
  • DuraCoat leverages advanced dual-polymer design to optimize line stiffness, abrasion resistance, and slickness. The core is enveloped by a supple material, promoting minimal memory and strong adhesion, while the outer layer boasts a robust composition that significantly enhances slickness and abrasion resistance.
  • Enhanced with EST+ slickness additive for unmatched durability, smoother shooting, and eco-friendly performance.
  • The option of a clear floating head or 10’ clear floating tip allows for the ultimate stealth when presenting flies to highly pressured fish.
  • Extremely versatile general-purpose taper designed for most freshwater species
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Extended head length for long-distance casts and superior mending ability
  • SA MAG S INFNTY WF X F (X = line weight)
