World-famous for its tight, round braid, smooth low-friction finish, and stretch-resistant performance, Micron is manufactured from premium Dacron fibers in our New York facility. Unlike looser, flat braids, Micron comes with zero twist, is virtually tangle-free and knots perfectly every time. Ask any fly angler who sees their backing more than most, and they'll tell you they use Micron — every time. Available in 20-lb and 30-lb test, in traditional white, high-visibility yellow or orange — or (new for 2014) blue.
