Material Premium Dacron
Construction 12-Carrier Round Braid
Cortland Micron Chartreuse is an all-purpose fly line backing made from premium Dacron fibers. Its tight, round 12-carrier braid creates a smooth, consistent profile that packs evenly onto the reel and moves through the guides with minimal friction.

Stretch-resistant construction, zero-twist handling and dependable knot performance make Micron a trusted choice for freshwater and saltwater fly reels. It is available in 20 lb and 30 lb strengths across multiple spool lengths for single-reel setups, multiple reels and shop spooling.

The high-vis Chartreuse color stands out clearly on the reel and makes the backing easier to track when a running fish carries the fly line into the backing.
