Renzetti R-Evolution Hair Stacker – Magnum
There is something magical about spun deer hairflies and some tyers have elevated it to an art form. The R-Evolution Hair Stackers are designed to make bundling hair bunches an easy and efficient task. The wide flared mouth makes for easier loading of the hair, and the square shape base prevents the stacker from rolling off the tying bench.
Manufactured from aluminum, this durable tool is built for consistent performance. Available in two sizes:
| Model | Tube Length | OD (Outside Diameter) |
|---|---|---|
| R Evolution Large | 1.75″ | 5/8″ |
| R Evolution Xtra Large | 2.25″ | 3/4″ |
The Renzetti product line is manufactured in the USA. Pat Ehlers from The Fly Fishers Shop in Wisconsin contributed to the testing of the Hair Stacker and Hair Packers.

This hair stacker makes bundling much faster and more consistent. The wide mouth allows easy loading, and the square base stays stable on my tying bench. I’ve used it for several weeks and it’s held up well under daily use.

The Xtra Large model fits my larger hair bundles perfectly. The aluminum construction feels solid and doesn’t bend or warp. It’s a reliable tool that saves time during tying sessions.

I appreciate the design improvements over older stackers. The flared mouth makes loading easier, and it stays in place on the bench. A little heavy for small hands, but worth it for the performance.
