Scientific Anglers FLY LINE BACKING - XTS GEL SPUN POLYETHYLENE - YELLOW 50lb

Notify me when this product is available:

If you’re looking for the best backing available, nothing can beat the XTS gel spun backing. With a diameter a fraction of the standard material, XTS retains its strength in the water, offers extreme abrasion resistance, and can fend off the worst the elements have to offer.

We sell it by the yard, so enter the number of yards you would like.

If you are also purchasing a reel we will install the backing on the reel. Be sure to select left or right hand retreive when purchasing the reel.

You can also just order backing in any quantity without a reel.
