Overview
This boat fly box holds up to 424 flies across double-sided rows, built in waterproof ABS plastic with a carry handle, sized to store everything from streamers down to small dry midges.
The extra-large slotted layout is aimed at boat anglers who want to consolidate several smaller boxes into one case rather than carry a slim, pocket-sized box. A hard-click snap seal is stated to work in both saltwater and freshwater use.
- 424 total slots, double-sided
- Waterproof ABS plastic body
- Hard-click snap seal
- Built-in carry handle for boat use
Who it's for
Anglers who fish from a boat and carry a large fly selection, from streamers down to small dry midges, are the target for this box. Anyone wanting a slim box for a vest or sling pack should look at a smaller model instead.
