Pine Squirrel Zonker Strips, Pine Squirrel hair is a relatively new item on the fly tying scene but it has become very popular in a short time. Flies such as the Sheila's Sculpin feature the material. Although the underfur can be used as dubbing – our favorite use of the material is as a zonker strip. We offer pine squirrel zonkers both in our standard (1/8″) zonker strip and in a micro cut (1/16″) for use on smaller flies.
