INCREASED STRENGTH – KastKing BackKast fly fishing line backing is woven using thin, high strength PE braid that delivers incredible strength for such a thin backing line. Available in both 20 & 30 lb. breaking strength options, means that you can put even more backing line on your fly reel before attaching your fly fishing line giving you additional fish fighting ability.

COLOR & LENGTH OPTIONS – BackKast fly fishing line backing is available in 4 color options to aid in visibility or to better match or compliment your choice of fly fishing line colors. Colors included solid chartreuse or white and is also available in an eye catching Chartreuse/Black or Orange/Black, multi-color weave. BackKast backing is available in either 100 yd. or 200-yard spools depending on the size of fly reel you are using.

LOW STRETCH – BackKast backing is made of Low stretch PE braided material that runs smoothly through guides and decreases resistance in the water while increasing angler control when a fish takes you deep into your backing. This low stretch also keeps hooks deeply seated in the fish’s mouth to reduce lost fish during hard battles.

SUPERIOR KNOT STRENGTH- Whether you are using loop to loop connections or tying a nail knot connection to non-looped fly fishing line, you can trust that your knots will hold fast to protect your expensive fly fishing lines and to avoid lost fish.

THIN DIAMETER – While BackKast backing is very strong, it is also thin which allows more backing to be loaded onto your reel prior to adding your fly fishing line. This will give you plenty of backing to fight large fish which may make long, powerful runs after being hooked.
