Real-world use and feel

On the practice green or during casual rounds, the JumboFlat 17 invites a sense of control. The flat surface helps you lock the grip in place, while the wider profile can reduce wrist movement and encourage a smooth, repeatable stroke. Expect a connection that feels grounded in your forearms and hands, rather than just your grip.

Who it’s for

Ideal for players who favor ArmLock putting and are curious about a larger, flat profile that supports a stable setup, steady alignment, and a confident feel through the stroke. It pairs well with players seeking a tactile grip that communicates contact and feedback without requiring extra force.

Care and tips

• Clean with a damp cloth to maintain tackiness over time.
• Avoid harsh solvents to preserve the grip’s texture and color integrity.
