Serious saltwater anglers, listen up - this Umpqua fly box is built to handle the tough conditions of flats fishing while keeping your flies organized and secure. The completely waterproof design (rated IPX 6.5, meaning it can handle being submerged up to 1 meter) protects your expensive flies from corrosion and saltwater damage. But the real magic is in the foam inserts - you get two different configurations to handle all types of saltwater flies. The first insert combines FlyTrap Foam and Mega Slit Foam, holding up to 120 flies of various sizes and styles. The second insert features deep Mega Slit Foam perfect for those larger flies with multiple hooks, storing over 45 big patterns securely. The high-density foam provides incredible holding power - your flies aren't going anywhere, even when you're bouncing around in a boat. The secure latch closure gives you peace of mind when traveling, and the see-through lids mean you can quickly spot what you need. It's surprisingly lightweight despite its rugged construction, and the ergonomic design makes it comfortable to carry all day. Whether you're wading the flats or fishing from a skiff, this box is like an insurance policy for your valuable fly collection.
