The Zippy Hair Stacker is a one-piece alternative to making sure that hair wings are full and even. The hinged design allows hair to be loaded easily, stacked, and removed cleanly. Magnets keep the stacker closed while in use, and the window in the base allows tyers to see when tips are aligned. From the biggest bass bugs to trout muddlers and compare duns, there is a perfect option flies and fibers of all sizes. Available in three sizes and 2 colors with an Unconditional Guarantee by Loon.
