The Renzetti R-Evolution Hair Packers by Pat Ehlers are available in Small, Medium, and Large to suit any tying style or fly size. Each size offers the same exceptional balance and control, allowing tiers to compress deer hair with uniform pressure for smooth, durable results. The Small packer is ideal for fine trout flies and compact patterns, while the Medium provides versatility for most freshwater and bass bugs. The Large model offers the power and clearance needed for dense saltwater or big-game flies. All three share Renzetti's signature precision machining, ergonomic comfort, and durable construction-delivering professional-grade results for every fly tier.
