Are All Fly Boxes the Same?

A proper option is going to depend on the flies it holds. You will want a small box to hold nymphs, another small one to hold dries, and other larger ones for streamers. You will always be in search of the perfect fly box.

Some people prefer a traditional book-style opening, while others prefer a two-sided design. Both have their advantages and disadvantages and you should try both to determine your best fit.

Flies Direct Waterproof Fly Box

Personally, I appreciate a clear design. This allows for quick and easy identification of contents without having to open and close different boxes.

I also appreciate a pre-slit, high-density foam design. Thankfully, this is the norm nowadays. This helps to increase the longevity of your foam and makes fly removal and loading quick and easy.

Most feature waterproof designs, though not all do. Be sure this is something you consider in deciding what you need most. This is usually a feature of the more durable, high-density plastic designs. A snap lock lid assists in this ability.

Features of Our Top Pick

So what makes a great fly box? It really depends on personal preference in many scenarios. Everyone has a different method for organizing and transporting their collection of flies. It will depend on which bag you use to fish and the size of your fly collection. 

However, there are a few things that I think should be a feature of all top pick, regardless of a user's particular preference. If I am purchasing a fly box, here are some things I like to look for.

Two sided storage with pre-slit foam is a must!

  • Pre-slit Foam: This type of foam design aids in foam longevity. It also makes fly removal and loading a quick and easy task.
  • Two-sided storage: Unless I need a tiny box for a certain application, having two-sided fly storage is a no-brainer. The more flies the better.
  • Clear lids: Personally, I like to be able to quickly and easily identify the contents of my box. I don’t always want to open and close a bunch of boxes. Clear lids make sure I don’t have to.
  • Durable: It should go without saying, but I want a fly box to be durable. I want a secure snap-lock design and a constructed foam impact-resistant plastic.
  • Waterproof: When you fly fish, you are obviously going to be around water. This lends itself to the possibility of dropping your fly box in the water. To better protect your flies, you don’t want them to get wet and therefore have to dry out all of your fly boxes and flies. Waterproof designs mitigate most concerns about this.

The Pros and Cons of Using a Fly Box

Selection is key to proper fly organization. In order to efficiently spend your time on the water, being able to quickly switch between flies is a must.

When you are sorting through, trying to figure out what the fish are eating, a properly organized set up will make this an easy task.

In addition to organization, these serve an important purpose of protecting your valuable flies. They keep them from getting crushed and from being continually soaked.

A single model can easily hold hundreds of dollars in flies, so you want to make sure it is going to hold up.

These also allow for easy transport of flies. Being able to stack several boxes in a bag or even slide one into your pocket makes getting out there to fish, the quick and easy task it should be.

However, fly boxes can become troublesome at times. It is easy to lose your organization and be left with a mess of flies.

Some people recommend using a very large master fly box and then transferring flies to a fishing box for the day. This ensures you will always be organizing flies and maintaining inventory.

How to Clean and Care For a Fly Box

Fly boxes, compared to other fishing gear components, should require less maintenance. Most are built to be simple and durable, lending to a long life. The biggest threat to a fly box is the possibility of being crushed. Thankfully, most are designed with such in mind.

Another weak point is the hinges. It may be good to periodically rinse your fly box free from grit and salt. Particularly if you have been fishing around saltwater.

Other than that, a quick rinse every now and then should be all it needs. If you have a waterproof box, this will be easy. In the end, just be careful of sitting on or crushing your boxes and they should enjoy a long life.

How to Use a Fly Box

All the options in the world won’t help you without proper organization. For some, they may fall victim to the tragedy of horribly messy fly boxes. This somewhat defeats the purpose of a fly box other than the protection it offers.

To ensure you can make quick and easy fly selections on the water, organization is paramount. In the video below, we discuss several different schools of thought in fly organization. Each person may find a different method to be suitable.

First off, you can organize them by size. Have a box for size 2-6 flies, another for 6-10, and so on. However, this can get cumbersome.

If you are just fishing with one type of fly, but modifying sizes, you will have to switch boxes. Also, in low light settings, identifying just what is in your box may become difficult.

You can also organize by fly type. In this scenario, you will have a box for bait fish patterns, another for leeches, hoppers, damselflies of different stages, and so on.

This is a method that works very well for some. With a variety of sizes of similar imitations in one box, it is easy to find what you are looking for.

However, what many choose to do is to plan ahead for a specific outing and compile an assortment that will match. In this video, we discuss having specific boxes for specific scenarios.

If you typically fish a few different fish types but always in consistent waters, consider having a box for each water. In this video, he discusses having a pond bass fishing box in addition to a trout stream box.

Each box has flies that you would only expect to use or want in that given scenario. You can also have a large master box and assemble a fishing kit for every fishing excursion. For many people, this type of organization tends to be very efficient for when you are out on the water.


Fly boxes are a key component to a fly fishing gear arsenal. They are the tool that protects and organizes your real weapons, your fishing flies. Having a fleet of fly boxes and system of organization will make fishing much easier and more enjoyable.

Every angler is going to need a selection of fly boxes and it may take some time to figure out just what you need. Thankfully, there are plenty of budget and diverse options on the market for you to try.
