Mill Stream's Fly Carrier accommodates 24 pre-rigged flies in a compact, easily transported package. Many times, the ability to change flies as conditions warrant means the difference between a hit and a miss. Rigging flies and leaders in advance is the only way to accomplish this change quickly and easily. The stretcher back is made of aerospace aluminum and is extremely lightweight. The unique stretcher blocks were designed to put the maximum number of flies in the minimum amount of space.
