Attach the fly and rigging patch to your vest and carry several different rigs. By pre-rigging and storing the rigs on the fly and rigging patch, all you need to do is remove the leader and tippet you are fishing and replace the entire rig with a new one from your patch. With multi-fly rigs like the hopper-copper-dropper, You save the time required to tie several knots. And the time to find the proper leader to turn the fly over.
This one includes a zinger ready to attach to your fishing vest.
The ridges at the top of the patch keep you from catching flies on clothing, and there is ample room to hold flies that you're done with.
NOTE: Flies not included.
