Piscifun Braided Fly Line Backing with Orange White Fluorescent Yellow Color 20lb 30lb 100yd 300yd

A good compromise between thinness and the ability to make blind splice loops. Extremely abrasion-resistant, virtually no stretch. Very low coefficient of friction won’t damage your fly rod guides. Retains 100% of its strength while in the water. Easier to knot than other brands that are very thin but have too tight a weave for a blind splice loop.
