Opst lazar line is the slickest, highest performing, farthest shooting running line available today. We searched for a long time for a monofilament running line that would perform well in both hot and cold conditions, that would withstand uv and seasons of use, and that would resist memory. The result is lazar line, a line with so little memory you will forget you're fishing mono. With a low, calculated stretch, lazar line ties extremely sleek and strong knots. It comes in 25, 20, 35, 40 and 50 pound test.
