The first and only Nylon Monofilament to transition in the water and physically change colour!

Berkley Trilene® TransOptic® Monofilament Line changes to bright gold in sunlight so you can see the ine, and therefore see more strikes. Transitions to clear when submerged underwater so the fish don't see it. The end result is more fish in the cooler.

This new breakthrough nylon co-polymer formula has excellent shock resistance, wet knot strength and abrasion resistance.
