The details of the line

From the shape of the taper to the finish of the coating.

CAD Taper

Our own taper

A custom taper designed in CAD and analysed with our casting simulator to study how the line unrolls.

Read more

River has a compound head with two body sections joined by a gradual transition. The taper determines where the line’s mass sits along the head. We study that distribution with our casting simulator.

How we study our tapers

Welded Loops

Quick connections

Welded loops at both ends for connecting your leader and backing.

Read more

The front loop connects to a looped leader. The rear loop connects to the backing. These connections let you replace a leader or disconnect the line without cutting its ends.

Arven Glide

Slickness additive

A slickness additive built into the coating to help the line move smoothly through the guides.

Read more

The additive is mixed into the coating during manufacture. Its job is to reduce friction as the line passes through the rod guides. Routine cleaning removes surface dirt that can interfere with that glide.

Arven Skin

Premium coating

The outer coating of River, with Arven Glide incorporated into its formulation.

Read more

The coating surrounds the braided core and forms the line’s outer profile, from the head to the running line. Arven Glide is the slickness additive incorporated into that coating.

Lift Tip

Floating tip

A floating tip that makes the drift easier to follow and helps lift the line from the water for the next cast.

Read more

The tip is the front end of the fly line, where the leader attaches. Keeping this section clean helps it stay on the surface, making it easier to follow the line and lift it from the water.

Low Stretch Core

Braided nylon

A low stretch core made from braided nylon.

Read more

The braided core forms the inner structure of the line and carries tension underneath the coating. Its low stretch construction limits how much the line lengthens under load.
