According to The Angler Sport Group, their new Serious Angler fly boxes are 'virtually indestructible.' The super-tough boxes are made from a fiberglass-reinforced ABS and polycarbonate plastic, so you can drop them or sit on them, and they won't break or crack. If they fall in the water, they'll float without leaking, thanks to a watertight seal-and-latch mechanism that won't open accidentally. Inside, the boxes are padded with high-quality etha foam to hold your flies. Available in green or tan, with clear or solid lids and adjustable lanyards, the boxes retail at $16 for a small size, $22 for medium (shown), and $26 for large; call 716-757-9958 for information.
