The Jailbird Mini is a smaller-profile mallet putter in the Ai-ONE family. It’s essentially a compact version of the classic “Jailbird” design: still a mallet-style head but sized for players who want a more compact feel at address while retaining the forgiveness and stability associated with a mallet.
It uses the “AI-ONE” insert — an insert engineered (with AI-derived contours) to produce consistent ball speed and roll, even on off-centre strikes. 

Key Features

• AI-ONE Insert with White Hot Urethane feel: The insert combines an aluminum backer (with AI-designed contours) and a co-molded White Hot–style urethane face — giving a familiar feel plus improved consistency across the face, even on off-centre hits. 

• Face-balanced / double-bend (DB) shaft option → Minimal toe-hang: At least one version of the Jailbird Mini (the “DB” variant) is face-balanced, making it especially suitable for golfers with a straight-back, straight-through putting stroke, or those who want minimal face rotation through the stroke. 

• Lightweight counter-balanced shaft (SL 90 Stroke Lab shaft): Odyssey uses a specially weighted shaft to shift weight toward the head and grip — improving balance and consistency of stroke, and giving better “feel” in the hands. 

• Compact mallet head — easier handling & alignment: Being a “mini” mallet — smaller than full-size mallet putters — it offers easier handling and a more controlled feel at address, which can suit golfers who prefer a stable but compact head size. 

• Premium finish & aesthetic: Navy blue PVD finish gives the putter a modern, premium look. 

• Customisable weighting (in some versions/aftermarket): Some versions allow adjustment of head weight or come with interchangeable weights — a useful feature if you prefer fine-tuning head feel.
