This is simply to say that choosing the best tool for the job is often a safe bet in anything you do. Fly fishing is a relaxing hobby and calls for the use of effective gear, such as the best fly fishing rod and the best fly line.

There are many different options when choosing a fly line but going with the first choice you see won’t cut it. Taking the time to see what else is available and what works best for your kind of fly fishing is not only practical advice; it’s prudent. With that being said, here are some of the best fly lines for bass fly fishing available on the market today.

Bass Fly Line Reviews

  • Type: Floating
  • Weight: 8wt

There are several good reasons why this RIO Mainstream Bass Fly Line is our best overall pick. It features a heavy front head, which means that you can throw big bass flies such as poppers or streamers with quite a bit of ease.

The line also features a heavier short head, which allows you to load your fly rod more quickly for more efficient casting. The front taper also effortlessly turns your bass flies over. Another excellent feature is that these lines have a low stretch core, which ensures that you get a better feel for your cast and increased line control.

Factors to Consider When Buying a Fly Line for Bass

As you can imagine, there are dozens of fly fishing lines for bass available on the market today. Each one of these options has its advantages and disadvantages. If you are going to find the best fly line for bass fishing, there are certain factors to consider. Here are some of the most important aspects to consider.

Fly ChoiceFly fishing for bass calls for the use of more than just one piece of fishing gear. That being said, one of the most important factors to consider before you buy a fly fishing line for bass is the kind of fly you are going to use. And to choose the best fly for bass, you first have to understand how bass behave:

They tend to feed in shallow water or water with lots of structures. You might not need to throw out a sinking line or sinking fly. This, in turn, means that you would be best served using a weighted forward floating line.

Bass also like ambushing their prey, which calls for larger flies. The best approach is to throw a large fly into tight cover. This calls for a fly line with a compact head and a short front taper.

In some cases, you will go fishing in windy conditions, which means you may want to use a heavy line.

Fishing Environments

While bass tend to feed in shallow water, they aren’t only found in shallow water. Sometimes, bass go deep underwater to keep warm or cool. In these cases, your best bet would be to fish around submerged structures, which might not be very easy to reach without using a sinking line.

When choosing a fly line for this kind of fishing, you need to consider the depth at which the bass or the structure around which they would be feeding can be found. If the structure is around 10 feet deep, you should consider using an intermediate fly line.

On the other hand, if you are concerned that the structure or the fish might be deeper still, using a full sinking line might be the better option.

Water Body Type

The body of water you will be fishing also has a lot to do with determining the kind of fly line you should use. There’s a big difference between fishing for bass in a lake where you are likely to see more success by throwing out a sinking line and fishing in a river where you might need to throw longer casts as well as make more delicate presentations.

Finally, there are factors such as color, price, and material. If you are going to be fishing in extremely busy waters, you might want to buy brightly colored lines just so that they’re visible to other anglers as well as yourself. The material from which the line is made determines how easy it is to cast and its durability after continued use.


Still have questions about the best fly line for bass? Read on for more valuable information.

What is the best color line for bass fishing?

Bass tend to have good color vision when looking at colors that fall under the medium to light red range. They are also quite good at spotting yellow greens and red-orange. Your best bet is to use lines that fall under blue or dark green because that’s where their color vision is weakest.

Must I choose a low-stretch line?

While you don’t have to choose a low stretch line, it’s important to consider that bass tend to have very hard mouths, and as such, you will have to exert a lot of energy to set that hook. Low stretch lines come in real handy here.

Can bass see braided lines?

Yes, fish can easily see braided lines, even though they tend to be quite thin. Monofilament lines are not quite as visible.

With the right tools, bass fishing can be a lot of fun. These fly fishing lines for bass are an excellent way to stock up on the right tools.
