What it is
The Hareline Fly Box Waterproof is a waterproof fly box built around silicone and magnetic inserts. The silicone grips flies with a self-healing surface, and the magnets add retention so hooks stay put even when the box gets bumped. It seals up with a secure latch closure and is also dustproof for keeping grit off your flies.
What to tie with it
This isn’t a tying material for the hook; it’s bench-to-water gear that helps you manage the flies you tie. Use it to store finished patterns, stage a day’s selection, and let damp flies ride open to dry after a session. The inserts support offset head-to-tail storage for bigger hooks and slit-style storage for small flies.
Flies and the fish they're for
Load one as a dedicated dry-fly box for trout on rivers and spring creeks, and keep another for nymphs and emergers when you’re fishing tailwaters or freestones. A separate box for streamer patterns like buggers and leeches is a common setup for trout and smallmouth in rivers and lakes, and it also translates to baitfish-style streamers when you’re chasing species that eat minnows. If you travel, it’s the kind of box you can organize by categories like scuds, terrestrials, and baitfish so you can quickly rotate between subsurface and surface options as conditions change.
