Overview
Anglers spooling a spinning reel with ultralight gear get a single-strand nylon monofilament here. The title describes an advanced polymer coating, a smooth finish and low memory, in a clear color that is hard for fish to see.
Low memory means the line leaves the spool in fewer coils, and the coating is aimed at abrasion from rocks and structure. The limit is strength, since a light breaking rating gives little margin against larger fish or heavy cover.
Who it's for
Casual and finesse anglers using small reels and light lures will get a manageable line. Anglers who fish near docks, rocks or heavy weeds, or who chase bigger species, will want a heavier rating.
Pros and cons
- Low memory comes off the spool cleanly
- Polymer coating for abrasion resistance
- Clear color is low-visibility
- Works in fresh and saltwater
- Light breaking strength limits target species
- Line diameter not listed
- Not a braid or fluorocarbon
Performance notes
Nylon mono stretches a little, which cushions sudden runs and helps hooks stay set. Low memory lets the line lie flat on the reel and cast farther. The polymer coating resists nicks from rough surfaces, but a light rating still fails under heavy loads.
