The Montana Fly Company (MFC) Hallock’s Brown Trout Poly Fly Box is a durable and functional fly box designed specifically for anglers targeting brown trout. Here are its key features:
Features:
1. Slit Foam Insert – The box features precision-cut slit foam that securely holds a variety of fly sizes and styles (nymphs, dries, streamers) without damaging delicate materials.
2. Compact & Lightweight – Made from rugged polypropylene plastic, it’s built to withstand rough handling while remaining lightweight for easy transport.
3. Secure Closure – Features a snap-latch or magnetic closure (depending on the model) to keep flies organized and prevent spills.
4. Brown Trout-Specific Design – Tailored for patterns effective on brown trout (e.g., Hare’s Ear, Pheasant Tail, Woolly Buggers), but versatile enough for other species.
5. Clear Lid (Optional) – Some versions include a transparent lid for quick fly identification without opening the box.
6. Portable Size – Fits easily in a vest, pack, or wader pocket (dimensions typically ~5″ x 3.5″ x 1.5″).
Ideal For:
– Anglers who fish brown trout streams and need a dedicated box for proven patterns.
– Guides or travelers needing a tough, water-resistant fly box.
– Those who prefer slit foam over silicone or compartmentalized boxes for versatility.
Alternatives:
– Tacky Fly Box – Silicone gripper slots (no foam).
– Fishpond Tacky Fly Box – Hybrid foam/silicone design.

– Cliff Outdoors Bugger Beast – Larger for streamers.
