C&F Standard System Foam

If you want to store a regular size for trout, this is the standard form.
. It holds more than it looks and won't crush the bottom of a vertically wound hackle.
The simple design, unified by 24 slits per tier, also allows you to manage the same flies by size in a single tier, such as four sizes of six flies each.

The 24-slit design makes it easy to keep track of your supplies, so you know exactly which flies you need to replenish after returning from the fishing grounds.
