Flambeau makes a great single sided fly box that has a clear lid which is great when you are fumbling around trying to find that perfect jig. Inovative Anglers also makes a great waterproof box with a clear lid and is very deep,which is also important for holding a variety of sizes of jigs.

Finsport has a great 3x4" soft box that is vented,and has a clip for attaching to anything.You can put the jigs that have been recently used in it to dry out before placing back into the jig box.

I would highly recommend using a single sided fly box to keep colors,especially marabou, from bleeding on to one another.Nothing worse than opening a box full of jigs to find out that you have a box full of 40 ugly pale pink colors that have all become one.

Hope this helps.
