How to Choose a Fly Box for Trout

A good fly box is one of the most important pieces of gear a trout angler can own. The right box keeps your flies organized, protected, and accessible on the water — so you spend more time fishing and less time fumbling through a tangled mess of hooks. With so many options available, choosing the right fly box can feel overwhelming. This guide breaks down the key considerations to help you find the perfect box for your needs.

Types of Fly Boxes

Compartment Fly Boxes

Compartment fly boxes feature individual compartments with snap-tight lids that keep flies separated and protected. They're ideal for dry flies, emergers, and other flies that can be damaged by being pressed against foam. For a dedicated dry-fly option, see our Dry Fly Box. The individual lids mean you only expose one compartment at a time — a huge advantage on windy days when loose flies can blow away. Our Pocket Compartment Fly Box is a proven pick in this category.

Compartment boxes come in several sizes:

  • Pocket size: Small enough to fit in a shirt pocket, these compact boxes are perfect for carrying a selection of your most-used patterns. Ideal for day trips when you don't want to carry a lot of gear.
  • Medium size: A versatile option that holds a good selection of flies without being too bulky. The 11-compartment design with individual snap-tight lids is particularly useful in windy conditions.

Silicone Fly Boxes

Silicone fly boxes feature a liner made of soft silicone rather than traditional foam. Silicone offers several advantages over foam: Our Double-sided silicone fly box is a great example.

  • Durability: Silicone doesn't compress or deteriorate over time like foam, maintaining its grip on hooks for years.
  • Odor resistance: Unlike foam, silicone doesn't absorb odors from fish slime, floatant, or other chemicals.
  • Waterproof: Silicone fly boxes are typically fully waterproof, keeping your flies dry even if the box gets submerged.
  • Hook grip: Silicone grips hooks securely without damaging hook points, even with repeated use.

Silicone boxes come in several configurations:

  • Double-sided silicone box: A versatile option with silicone on both sides, holding a large selection of flies. Perfect for nymphs, wet flies, and streamers.
  • Silicone slim box: A slim, low-profile box that fits easily in a vest or pack pocket. Waterproof and durable, with a silicone liner that holds flies securely.
  • Large silicone slim box: A larger version of the slim box, ideal for euro nymphing setups where you need to carry a large selection of barbless jigged nymphs.

EVA Foam Floating Fly Boxes

EVA foam fly boxes are made from closed-cell foam that floats if dropped in the water — a significant advantage for clumsy anglers or those fishing from a boat. The magnetic closure keeps the box securely shut, and the slit foam holds dry flies and other patterns securely without damaging hook points. For an ultralight option, see our Silicone Slim Box.

The floating dry fly box is particularly well-suited for Chubby Chernobyls and other large foam dry flies, which can be difficult to store in compartment boxes due to their bulk.

Specialized Fly Boxes

In addition to general-purpose fly boxes, specialized boxes pre-loaded with curated fly selections are an excellent option for anglers who want a ready-to-fish setup:

  • Small Nymph Fly Box: A double-sided silicone box containing 61 tungsten bead nymphs and subsurface flies — everything you need for a day of nymph fishing.
  • Large Silicone Slim Euronymph Box: A waterproof slim box with 72 barbless jigged euro nymphs, perfect for dedicated euro nymphing anglers.
  • Nymph and Stonefly Box: A double-sided silicone box with 30 nymphs and 30 Pat's Stoneflies — a deadly combination for any trout river.
  • Tungsten Squirmy Fly Boxes: Available in pocket and full-size versions, these boxes come pre-loaded with tungsten squirmy worms in a range of colors.
  • Dry Fly Box: A floating EVA foam box with 50 Chubby Chernobyl dry flies in a range of sizes and colors.

How Many Fly Boxes Do You Need?

Most experienced trout anglers carry at least two or three fly boxes on the water:

  • One box for nymphs and wet flies
  • One box for dry flies and emergers
  • One box for specialty patterns (eggs, squirmies, streamers)

The key is to keep your boxes organized so you can find the right fly quickly when the fish are rising. Label your boxes or use different box styles for different fly types to make identification easy.
