## Overview

Stren MagnaThin Monofilament offers a remarkable strength-to-diameter ratio, allowing anglers to use thinner lines without sacrificing durability. With 330 yards of clear, low-stretch line designed for fast sinking and precise casting, it’s engineered for serious anglers targeting line-shy gamefish in clear water.

## Description

AMAZINGLY THIN, ASTONISHINGLY STRONG Natural lure action and low visibility are two features that position Stren MagnaThin as a top choice for clear water or line-wary gamefish, yet the defining feature of this remarkable line is its exceptional strength-to-diameter ratio. Anglers can drop down a size or two without sacrificing strength. When strength, thin diameter and casting accuracy count, knowledgeable anglers count on Stren MagnaThin.

Review: Great line! - This might be my favorite monofilament line ever. I use the 4 lb (2 lb diameter) on my ultralight, and the 8 lb (6 lb diameter) on my medium. The casting distance is unreal, and the strength is about normal for monofilament. I prefer the low visibility green color. Trilene XL is a similar concept of thin line, but this is executed way better IMO.
Review: Old Skool Goodness - I have used stren for 40 years. Mono has fallen out of favor lately, with Braid and Fluorocarbon lines on most anglers reels, and don't get me wrong, I use both, but when I want mono, I want stren magnathin. Simply the best freshwater mono there is and won't break the bank.

## Features

- Smaller diameter for less water drag, faster sinking and improved lure action
