Ultra-light Euro Nymph fly lines

Ultra-thin & extremely light fly lines, perfect for Euro Nymphing

These ultra-thin fly lines have been specially developed for use in Euro Nymphing. They are extremely light so that you can keep the fly line completely out of the water even over long distances when accompanying the drift of your nymphs. The big advantage of these Euro Nymph fly lines over the even lighter monofilament lines is their versatility. Not only can you fish nymphs very effectively and successfully with them, but you can also cast dry flies, wet flies and emergers well with them. So, if the fish suddenly start rising on hatching insects when you are out on the water and Euro nymphing, you are ideally equipped with such a fly line, even if these lines with their low weight are of course not specially designed for this. Many of the ultra-light Euro Nymph fly lines already have an incorporated sighter on the front tip, so you only need to rig the tippet to get started.

The idea of Euronymphing is based on the lightest possible line, which allows you to keep large parts of your rig out of the water, whereas only the strictly necessary part of the rig is submerged. In this way, your line is not affected by currents or obstacles and your nymphs can drift close to the bottom very naturally and at the right speed.

The use of pure monofilament lines is not permitted in official fly-fishing competitions. To circumvent this regulation, special ultra-thin fly lines with a diameter of 0.55 mm have been developed. Even though they are super-thin compared to classic fly lines, they still weigh more than a monofilament line. At first glance, they do not appear to be ideal for Euronymphing. The opposite is actually the case.

Even though a practically weightless mono line is extremely effective for Euronymphing in certain situations, an ultra-light fly line offers you a number of advantages that a mono line simply does not have. But before we go into the advantages in detail, we would like to emphasise once again that these special fly lines are indeed extremely light. At short distances, the difference to a monofilament line is only very slight.

Even though the weight of the Euronymph fly lines may only be light, the rod loads up better with their help than with the weight of the nymphs alone. In this way, you can use extremely light nymphs and still present them at greater distances. If there is an unexpected hatch during Euronymphing and the fish start to rise, you can even tie on a dry fly. Of course, ultralight fly lines are not intended for this application, but you can still fish with them with a certain degree of effectiveness even with the dry fly, which is impossible with a pure monofilament line.

Due to their weight, ultra-thin fly lines offer you a certain degree of casting precision even in light winds. In strong winds, Euronymphing is almost impossible even with these lines, but in moderate winds you will certainly be able to cast better and more accurately, especially if you have to place your nymphs in confined spaces.

The last 2 advantages of a Euronymph fly line over a monofilament line may only be partially significant but should not be underestimated. This is because the fly line has a lower memory effect than mono line and always stretches perfectly, even at low temperatures, without having to be smoothed by hand previously. And finally, unlike mono line, the fly line does not stick to the rod blank in the rain and therefore always glides smoothly through the running guides.


Although it is relatively easy to start fishing at Euronymph, many people don't know how to take their first steps in technique and equipment. This is why we have put together an COMPLETE TUTORIAL TO EURONYMPH in which we cover all the main topics in detail, such as:

  • How the Euronymph technique was born
  • What are its strengths compared to other fly fishing techniques
  • What specific equipment to buy
  • What are the most commonly used rigs
  • How to cast and drift your nymphs effectively
