Scientific Anglers XTS Gel Spun Backing allows more reel capacity thanks to advanced technology.

• Exceptionally small-diameter backing is braided to increase the inherent strength of the material.
• Up to 75% more reel capacity than standard material.
• Stronger than steel in equal diameters.
• Retains 100% strength while wet.
• Extremely low diameter allows for more yardage on the spool.
• Designed specifically for fly fishing with a smooth coating and low coefficient of friction (COF) that minimizes wear on guides.
• Extremely high abrasion resistance.
• Extremely high visibility.
• Impervious to UV rays, gas, oil, salt, and other elements.
• Material: Braided gel spun polyethylene.
