Fly Fishing lines

Brittany Fly Shop - A great selection of quality fly fishing lines

The fly line is an essential part of your kit.

It is the link between your rod and your fly.

But how do you choose the right line? It must be suited to your style of fishing and the power and dedicated line weight of your fly rod.

Fly lines from #2 to #5 weight are mostly designed for trout and grayling fishing in rivers.

Fly lines #6 and #7 weight are perfect for reservoir and lake fishing

Fly lines #7 up to #15 weight and above are designed for hunting predators in saltwater and freshwater.


We have selected the best models from the best brands on the market to meet all your needs, in both fresh and salt water, from floating to extremely fast sinking to cover most fishing situations and deliver your fly at the right depth in the water column.

We particularly like the Guideline, RIO, Scientific Anglers, Airflo and Cortland lines, which are perfect for European sea bass fishing and tropical fishing.

You will also find Snowbee and Royal Wulff lines, which are ideal for fine and delicate fishing in rivers, lakes and reservoirs, with long distance shooting capacities for the later.
