The Berkley Trilene Micro Ice Filler Spool is a premium ice fishing monofilament engineered for ultra-fine presentations in the harshest cold-water conditions. Built specifically for hardwater anglers, this line delivers a rare combination of low stretch, high sensitivity, and strong diameter-to-strength performance, helping you detect subtle bites and land more fish when conditions get tough.
Designed to stay flexible in freezing temperatures, Micro Ice resists stiffness, memory, and coiling — common problems that can ruin finesse presentations under the ice. Whether you’re targeting panfish, crappie, perch, walleye, or trout, this line gives you the control and responsiveness needed for precise jigging and quick hooksets.
Anglers consistently rely on Micro Ice as a go-to winter mono because it balances strength and finesse without overcomplicating your setup.
