Rio Gel Spun Fly Line Backing 65 lb 200 yd

RIO's premium 65 lb GSP backing is built from 8-carrier, tightly braided fibres sourced from Japan, producing a round, consistent profile that stacks cleanly and evenly on any fly reel. The result is backing that's stronger, softer, and smoother than standard Dacron — with a slim diameter that maximises backing capacity without sacrificing strength. The multicoloured braid changes colour every 10 metres, adding a functional depth marker and a striking visual complement to your reel. Rated for everything from panfish to blue-water heavyweights — GTs, billfish, and tarpon — this is backing built to handle whatever end of the spectrum you're fishing.
