SF Large Waterproof Fly Box For Fly Fishing - Double Sided Foam

Our review of the SF Large Waterproof Fly Box finds it best suited for anglers who want a rugged, high-capacity way to carry a wide variety of flies and small jigs. The single biggest reason to buy is its practical double-sided design with foam storage that protects hooks and maximizes capacity, making it a useful choice for long trips or mixed fly collections. The box balances toughness and portability with an ultra-thick ABS shell and a sealable, rotating internal plate for quick access.

Key Features

• Size: At 6.1 in x 4.0 in x 1.8 in it fits comfortably in a vest pocket or tackle bag while offering significantly more room than single-layer boxes.
• Double-sided storage: The two-layer layout effectively doubles usable space so an angler can carry dry flies, nymphs and streamers in one compact box.
• Sealed and waterproof: The coaxial wheel switch lock and thick ABS shell keep water out and help protect hooks from the elements.
• Rotating internal plate: The internal storage plate rotates 180 degrees for fast access, letting users organize and reach flies without removing trays.
• Durable foam inserts: Foam storage boards are heat- and water-resistant for long life and reliable hook retention.
• High capacity: The design can hold up to 234 small lures or flies, reducing the need for multiple boxes on a trip.

Who It's For

The SF Large Waterproof Fly Box is aimed at freshwater and ice anglers who carry a varied selection of flies and want a single, durable container that organizes wet and dry patterns side by side. It works well for day trips where capacity and quick access are priorities and for anglers who prefer plastic housings and foam retention over magnetized or slotted plywood systems.

Less suitable users include those who need ultra-lightweight, minimalist solutions for ultralight hikes or anglers who require specialized compartments for very large streamers; the box prioritizes capacity and protection over minimal weight and extreme bulk for oversized flies.

Pros & Cons

Pros

• High-capacity double-layer layout holds many flies and reduces the number of boxes needed.

• Rotating internal plate and coaxial wheel lock make access quick and secure.

Cons

• Some customers report mixed opinions on the seal, so absolute waterproofing under extended immersion may not be guaranteed.
• The larger size adds a bit more bulk than minimalist fly wallets.
