Trout fishing to the next level


The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude will shoot farther and last longer than any other line on the market. It’s slickness down to a science.

Fly fishing for trout has never been so smooth, especially with a triple-textured line. Featuring our unparalleled AST Plus slickness additive, the Amplitude Trout is slicker than any trout taper we’ve ever made and will last over 8 times longer than other lines on the market.

Built for precise presentations and those who love dry flies, the Amplitude Trout is a game-changer on any stream, anywhere.
