Overview
Sized to match a sheet of A4 paper, this slim, clear-lidded fly box holds up to 450 flies across dry, wet, nymph and streamer patterns, built from durable PP plastic with high-density foam to keep hooks pinned in place.
At roughly 12 by 8.8 by 0.92 inches, the box is thin enough to slot into a vest pocket, boat compartment or drawer without taking up much room, while the 450-slot foam interior is built for anglers who carry a wide fly selection rather than a handful of patterns.
- 450-slot capacity, holds flies of all major types
- Clear PP lid for at-a-glance viewing
- Slim, A4 paper-sized footprint
- High-density foam secures hooks in place
Who it's for
Fits anglers who want one large box to carry a full fly selection for a day on the water, including boat and competition anglers. Not for someone who only carries a few flies and wants something more compact.
Pros and cons
- Holds up to 450 flies in one box
- Clear lid shows contents without opening
- Slim profile fits flat storage spaces
- Works across dry, wet, nymph and streamer patterns
- Bulkier than a single small fly box
Performance notes
High-density foam inside the box grips fly hooks securely, and the clear PP lid lets an angler see the contents without opening it. The slim, A4-sized profile is meant to fit flat storage spaces like a vest pocket, boat hatch or gear bag pouch, and the 450-slot capacity covers dry, wet, nymph and streamer patterns in one box.
