Having good fishing line is perhaps one of the most important things to keep in mind. Fishing line needs to be durable, have a high tensile strength, it shouldn’t absorb water, have low memory, and it needs to be heavy enough to reel in the fish on your hook. Now, there are quite a few types of fishing line out there.

The question of the day is what is Trilene fishing line made of? Now, we want to mention that this question is just a little bit misleading. This is because Trilene is actually a sub category of a brand name, not a type of fishing line.

The actual brand name here is Berkley, which is a highly trusted brand name in the fishing game. Berkley makes this so called Trilene fishing line, and it comes in various types and styles.

Trilene Fishing Line – The 3 Types

There are three main types of fishing line that you can buy. These include the good old monofilament line, fluorocarbon line, and braided line too. The bottom line is that Berkley Trilene does come in all of these varieties.

It’s a big time brand name and the Trilene line of fishing lines is super popular. Let’s take a look at the strengths of each type of line, and what the differences are between them.

1. Trilene Monofilament Line

Monofilament line is the kind of fishing line that has been around the longest, for well over 60 years. It is one of the most commonly used types of fishing line.

These lines are made out of nylon, or actually out of multiple nylon based polymers.

Monofilament is quite popular for a variety of reasons. For one, it tends to be quite cheap. Also, you can fit quite a bit of it onto any fishing reel.

Moreover, it comes in many different colors and weight/strength levels.

On that same note, you can find good monofilament fishing line with low memory, plus ones that are quite strong too.

Now, monofilament line does have some downsides. For one, it is not totally invisible under water. Fish will most likely be able to see it, especially if the weather and water is just right.

Also, it tends to absorb quite a bit of water, especially with prolonged use. After it has absorbed a lot of water and softened up, it can lose its strength by as much as 30%.

Another problem with monofilament line is that it stretches a lot, which does decrease sensitivity.

2. Trilene Fluorocarbon Line

Another very popular type of fishing line is fluorocarbon line. This is a newer type of fishing line, and although it may look like monofilament line, it is quite different.

Fluorocarbon line is made out of fluorine, carbon, and hydrogen, plus it involves a complex chemical bonding process.

First and foremost, the biggest advantage that you get with fluorocarbon line is that it refracts light. Simply put, it virtually vanishes under water.

It’s a big bonus when it comes to fishing because the line itself won’t scare off the fish.

What can also be said is that fluorocarbon line tends to have a very high level of resilience to sunlight, chemicals, and temperature.

It also has high tensile strength, plus it doesn’t really absorb water either. Moreover, it is very dense, so it will sink quickly, which can be good or bad depending on the kind of fishing you are doing.

Now, the big downside to fluorocarbon line is that it has weak knot strength and is hard to tie knots with. Many anglers have lost lures due to this knot strength and tying problem.

3. Trilene Braided Line

The other kind of popular fishing line is braided line. This is a very new invention and it is definitely quite unique too. Braided line is made out of super tough polyethylene.

They feature hundreds or even thousands of miniature strands that are all woven together to form a small yet tough braided line.

Many smaller lines put together and properly braided are always going to be super tough. What is awesome about braided line is that it is super thin, and can in fact be thinner than monofilament line, which seems odd seeing as a braid sounds bigger, but it’s not. This means that you can fit a whole lot of braided line on a single reel.

Furthermore, braided line is super tough, perhaps the toughest of all types of fishing line out there. Also, unlike monofilament line, braided line has barely any stretch, which means that it is super sensitive and easy to feel nibbles with.

However, depending on your fishing situation, having no stretch can also be a bad thing. However, braided line can be a little hard to tie into knots. It also tends to be fairly visible under water, thus potentially spooking prey.

Other Things To Consider When Buying Trilene Fishing Line

There are a couple of other main considerations to keep in mind when buying fishing line, Trilene or otherwise.

Test Weight

For one, you definitely need to pay attention to the test weight of your fishing line. Simply put, you need the line in question to have a weight rating strong enough to catch the fish you are going for. Test simply refers to line strength.

For instance, if you have a line that is 30 pounds test, it means you can go for 30 pound fish, or if the fish are big fighters, maybe just 25 pound fish.

At any rate, you need to match the test of the fishing line with the weight and strength of the fish you are going for.

It’s important to note that if the line is not strong enough, or if the pound test is too low, the line will probably snap when reeling in a heavy fish.

Getting line that is way too heavy for the fish you are going for can be a little problematic, but not nearly as much as if the line is too light.


The color of the fishing line you are using is definitely important. First and foremost, fluorocarbon line is the most popular in this sense because it does virtually disappear under water, thus becoming nearly invisible to fish.

Braided line is usually always going to be fairly visible, but not too bad. Both with braided and monofilament fishing line, color is important to keep in mind.

Clear monofilament line is pretty good in terms of visibility. Green line is good for blending into the water so fish cannot see it, but it can be visible to fish if the water itself is very clear.

Red line is a bit of a mystery, as it can be easily seen right under the surface of the water, yet is said to be nearly invisible under a certain depth.

Yellow line is a good choice for muddy or dirty water as it will blend in, but don’t use it for clear water, as fish will almost always see it.
