Scientific Anglers XTS Gel Spun Fly Line Backing

Micro-diameter gel-spun backing adds strong, high-capacity support to fly reels.

Scientific Anglers XTS Gel Spun Fly Line Backing uses gel-spun polyethylene in a micro-diameter construction. It increases capacity up to 75% compared with standard material, retains full strength when wet, and provides high abrasion resistance. The smooth coating and low coefficient of friction help it handle cleanly.
