Semperfli is a manufacturer of quality fly tying materials based in the UK. We make our own materials - we have our own team of dyers, spoolers and packaging specialists on our premises in the North of England.

We have always been known for one of our earliest products, the super strong Nano Silk fly tying thread, but we have a wide range of specialist materials that we are very proud of including the amazing Classic Waxed Threads for example! Our catalogue showcases our full range of materials and, we hope, will inspire you and your fly tying thanks to the work of our Pro Team shown in it - semperfli.us/2019catalog

We are delighted to supply specialist fly tying shops and distributors around the world who share our enthusiasm for fly tying and who ultimately get our materials into the hands of passionate fly tyers everywhere.
