These are two super-slim boxes that you can cram full of small nymphs, midges, and little streamers. The super-light boxes feature see-through lids and don't seem to take up any space. They're just the right size for wader pouches and long narrow pockets and they're so thin, most pockets will accommodate several.
Very easy accessibility, in vest pocket, wader pocket etc. Slim/sleek look.

Wapsi Ultra Thin Slim Jim Box
Another good product from Wapsi.....I prefer the boxes with the magnet bottom as apposed to the foam inserts. It is a little thin for larger flies but I usually carry a small Tenkara fly box for a limited number of dry and small streamer flies. When you are hiking 3 to 7 miles into a high mountain lake and fishing at 10,000 to 13,000 feet. The right selection of flies is of the most importance not bringing every fly box and pattern you own.
