TESTIMONIALS:

“

“130 pound BFT on the 50lb Opsin Fluorocarbon. This has never happened to me but it seemed like every cast equaled a hook up. Love this line. I passed off my rod several times when others could buy a bite. Opsin for the win!”

— L. Hinojosa

“

“I began using Opsin early on and was impressed by its top-notch quality. After meeting the creator, I realized his dedication as a family man reflected in his product. #opsingetsbit was coined. It’s now essential for the fishing community, on par with knife jigs. If you’re looking for effective bait, try the deckhander pack. Thanks to the team for making customers feel like family.”

— Justin Rhoads

“Opsin has been our go-to fluorocarbon choice for all types of trips this year.”
