This is the original, the tubing that Mikael Frödin and Håkan Norling have used since the early ’80s. This is the tubing that changed the use and looks of tube flies forever. It’s adapted to all kinds of modern tube flies, more flexible and durable than any other tubing material. The tubing comes in four diameters; XS fits in M and S in L. 12 different colors in four diameters give almost endless possibilities. No matter you tie big or small flies, with or without cones, fish loose hook or fixed. There is only one original and the FITS Tubing is simply the best there is.
