Thanks to its high technology fluorocarbon coating, this fishing line has an outstanding smooth surface and is almost waterproof, which means that it retains almost all of its strength even when it is wet, unlike all other conventional lines that can become weaker up to a 15% factor.
The amazing fact about this line is that, despite its top knot strength, it has very limited stretch factor (20-24%), which improves dramatically the feeling of the bite. Take a look at most of the lines on the market: if they are strong in the knot, they stretch too much, and thus you don't "feel" the fish!
