Used this line for permit fishing in the Gulf and noticed a significant difference in visibility and performance. The line stays clear and doesn’t tangle easily. Very smooth and durable under heavy use.

Great clarity and feel. The DuraCoat technology really stands out—less friction and better resistance to abrasion. Works well in both wind and rough conditions.
Andrea Stewart –
Solid performance for saltwater fly fishing. The transparency helps with spotting fish, and the line holds up well during long casts. Slight stiffness at the tip, but manageable.

This is the first clear fly line I’ve used that doesn’t feel slippery or break down quickly. The floating tip works well with my casting technique and keeps the line clean.
