About us
Opsin Fluorocarbon Line
Opsin Fluorocarbon was founded in 2020 with a clear mission: to give anglers the best shot at success on the water. What started as an idea between two fishing fanatics, Greg Brown (Founder) and Alan Bierig (Co-Owner), has grown into a brand trusted by anglers worldwide. We’re not just a company—we’re a group of people who live and breathe fishing. We’re obsessed with the process, because in fishing, details matter.
When it comes to gear, we believe in doing things right. That’s why our 100% fluorocarbon leader lines are crafted in Japan using an advanced "slow extrusion" process. This innovative technique produces lines that are virtually invisible underwater, incredibly strong, and as thin as they come—giving you the edge needed to outsmart even the wariest, line-shy fish. These are the lines anglers count on to make every trip count, whether they’re chasing bluefin tuna or hunting trophy bass.
At Opsin, fishing is more than just a sport—it’s a way of life. It’s about those early mornings, the adrenaline rush of a hookup, and the stories you share after a great day on the water. We’re committed to producing gear that gives you the confidence to focus on creating unforgettable moments.
Whether you’re out for a trophy, filling your cooler, or just enjoying the water, Opsin Fluorocarbon has your back. Welcome to the Opsin family—let’s make every cast count!
Tight lines,
The Opsin Team
