Silicone Slim Box

The Slim Box proves you don't have to choose between capacity and pocketability. Its secret is the silicone liner: tougher than standard foam, it holds hooks firmly without the tear-out that ruins foam boxes over time — and unlike foam, it never absorbs water, fish slime, or that unmistakable old-fly-box funk. Fully waterproof, it shrugs off rain, splashes, and the occasional dunk.

The slim profile disappears into a shirt pocket, wader chest pack, or the front of a vest, making it the ideal minimalist box for a quick evening session or a hike-in trip where every ounce matters. Don't let the size fool you — the efficient layout still carries a serious selection.

Buy it empty, or let us fill the deal: purchase $125 or more worth of flies and receive one of these silicone slim boxes with your order. Your flies deserve better than a soggy foam box.
