RIO Multi-Color GSP Gel Spun Fly Line Backing gives fly anglers high-capacity backing with big-fish strength and a slim diameter, making it a strong choice for everything from panfish and trout to salmon, steelhead, saltwater gamefish, and other hard-running species that can take you deep into the spool. This premium 65 lb. 8-carrier backing uses eight tightly woven fibers to create a round, strong, softer, and smoother line that stacks neatly on the reel, and its diameter matches regular 30 lb. backing so anglers can pack in more strength without giving up space. The multi-color pattern changes every 10 meters for added visual reference during long runs, and the color-forward look adds a functional splash that complements modern fly reels and lines.

• Premium 65 lb. 8-carrier GSP backing delivers high breaking strength with a round profile for smooth reel stacking
• Same diameter as regular 30 lb. backing helps increase backing strength without taking up extra spool space
• Multi-color pattern changes every 10 meters for quick visual reference during long runs and line management
• Strong, smooth backing suits a wide range of species from panfish and trout to salmon, steelhead, and ultra-big game fish
