Frödin Improved Tube System – the original Scandinavian tube system that changed tube fly tying world wide forever. The foundation of the system is the original coloured tubing that comes in 4 sizes. To balance the fly, to create different profiles and to fish at different depths we offer several types of cones and weighted tubes, all in 3 sizes. FITS is all you need to make any tube fly swim like nothing you've seen before. And remember – There's only one original!
