Polyleaders are durable with a low memory and built-in shock absorption.
The Polyleader is built on the same principle as a fly line with a core and coating and is an extension of your fly line. The butt section of the leader has about the same diameter as the end of the fly line. It also has an integrated loop in the thick end, which facilitates a quick waterside change.
Availabe in a wide range of lengths which allows you to really fine tune your presentation and find that perfect cast on any given day.
