Custom Manufactured Fly Lines

How a Fly Line is Made

Most fly lines are manufactured with a core of braided nylon or dacron. This core is then coated with PVC, which has been treated with various substances such as microscopic glass spheres for floatability or other additives that cause the line to sink at various desired rates (called multiple density production). This gives the line the desired characteristics. The PVC coated core is then processed to obtain the required taper (e.g., weight forward, double taper, etc).

Different fishing conditions require different line characteristics. For example, our salt water lines are designed to be stiffer and slightly more durable as they are usually used in tropical salt water conditions. On the other hand, our conventional lines are softer and more flexible as they are used in many different fishing situations in the Northeast and Mountain regions of North America.
