  • KastKing Features & Specs
  • SPECIAL DESIGN - Propel fly fishing lines are 90’ long and feature a weight forward design and high floating characteristics that deliver long, effortless casts and easy line turnover because of our unique belly design, short front taper and long running line.
  • BETTER PERFORMANCE - Each Propel fly fishing line is made with a braided, memory free core and uses our super slick, high float surface that improves performance, casting distance and keeps the line floating high in the water for better fly presentations.
  • WELDED LOOP - All Propel fly fishing lines include a single welded loop on the front of the line that makes attaching leaders quick and easy. Welded loop connections slide easily through the guides without hesitation and save set up time.
  • BACKING INCLUDED - Propel fly fishing lines come pre-spooled in the box with either 20 or 30 lb. braided fly fishing line backing to help you save even more time and money. The backing comes in lengths from 50-100 yards depending on the weight of the fly fishing line. Propel fly fishing lines are available in lines weights from WF3 to WF8 and come in three popular colors.
  • BIOSPOOL - KastKing has always been a Green Company that has fostered environmental responsibility. To meet that expectation, all KastKing fly fishing lines are spooled on our award winning biodegradable BioSpool, which is made from wheat straw and unlike plastic spools, will decompose naturally to reduce landfill bulk. KastKing is a sponsor of Trout Unlimited and we proudly support the efforts of their 300,000 members nationwide to develop and restore natural trout habitat.
