Odyssey Ai-ONE Square 2 Square Max Stripe putter

The MAX STRIPE is the newest shape in the Odyssey Square 2 Square line and the most stable Odyssey head design, boasting an MOI exceeding 6,000 (Izz). Engineered for golfers who want a simplified, repeatable square-to-square stroke with maximum stability, it combines the AI-designed Ai-ONE insert with bold Versa 90 alignment graphics and a modern center-shafted construction that keeps the face square from takeaway to follow-through. This version features a bold white paint fill on the raised center section, making alignment extremely intuitive, and ships ready to play with an Odyssey SL 90 Stroke Lab shaft and an Oversize grip. It is the ideal choice for players with a straight-back, straight-through or mildly arcing stroke who demand maximum forgiveness, consistent distance control, and effortless aim.

Key Features

Ai-ONE Insert: AI-engineered contours on an aluminum backer, co-molded with White Hot urethane, deliver consistent ball speed across the entire face.
MOI Over 6,000: The MAX STRIPE is Odyssey's most stable Square 2 Square shape, resisting twisting on off-center strikes for reliable direction control.
Versa 90 Stripe Alignment: Bold ball-width white stripe across the raised center section makes it exceptionally easy to aim and promotes a straight stroke path.
Center-Shafted Stroke Balanced Design: The shaft is centered directly on the putter's CG plane, causing the head to rest toe-up and eliminating unwanted torque throughout the stroke.
Built-In 3.3° Forward Shaft Lean: Pre-sets the hands in a forward press position at address, reducing face-opening tendencies without any manual adjustment.
SL 90 Stroke Lab Shaft: Lightweight steel shaft with a counterbalance weight in the grip end promotes a smoother, more consistent putting tempo.
Oversize Grip: The standard-length Oversize grip encourages a relaxed, arm-driven stroke and reduces unwanted wrist action.
Navy Blue PVD Finish: Premium dark navy PVD coating gives the head a rich, distinctive look and reduces glare at address.
Includes Headcover: Ships complete with a matching headcover to protect the mallet head during transport and storage.

Technology in Detail

Ai-ONE Insert

Designed using Callaway's industry-leading artificial intelligence and supercomputing capabilities, the Ai-ONE insert features precisely engineered contours machined into the back of an aluminum backer plate. These contours flex and rebound at impact to maintain consistent ball speed across the entire face — even on off-center strikes that would rob distance with a conventional insert. A grooved White Hot urethane layer is co-molded directly onto that aluminum backer, delivering the soft, satisfying feel that Tour players and amateurs have trusted for decades. The unique champagne-toned finish of the insert face complements the dark navy blue PVD coating of the head, creating a visually rich and premium look at address. The result is a multi-material construction that simultaneously maximizes forgiveness and preserves the classic White Hot touch.

Versa 90 Stripe Alignment System

The MAX STRIPE's bold, ball-width white stripe is painted onto the raised center section of the mallet head, creating an instantly recognizable reference line that links your eye directly to the target. This Versa 90 alignment graphic is positioned at 90 degrees to the face, giving you a clear visual cue that the face is square before you even take the club back. The high-contrast white-on-navy color scheme works in bright sunlight and on shaded greens alike, helping you maintain focus and confidence through the entire pre-shot routine. For golfers who struggle with misalignment or inconsistent aim, the MAX STRIPE provides a simple, repeatable visual checkpoint that takes alignment guesswork out of the equation.

Center-Shafted Stroke Balanced Design

Unlike traditional putters — even face-balanced models — the Square 2 Square line places the shaft directly on the plane of the putter's center of gravity. This perfectly balanced configuration eliminates the detrimental torque that causes conventional putters to rotate open or closed during the stroke. The head naturally rests in a toe-up, reverse-torque position at address, meaning the face wants to stay square to your arc throughout the putting motion without requiring any manipulation from your hands or wrists. By removing unwanted face rotation from the equation, players gain markedly improved accuracy and consistency on the greens without having to overhaul their existing mechanics. The center-shafted design is especially powerful for golfers who prefer a straight-back, straight-through path.

Built-In Forward Press & MAX Mallet Stability

A built-in 3.3° of forward shaft lean is engineered directly into the hosel geometry, automatically presetting your hands ahead of the ball at address. This eliminates the tendency to open the face that often occurs when golfers manually apply a forward press, giving you a consistently solid impact position on every stroke. Combined with the oversized square-mallet head geometry, the MAX STRIPE achieves an MOI exceeding 6,000 — making it the most stable shape in the entire Square 2 Square family. The perimeter-weighted construction resists twisting so effectively that even putts struck noticeably off-center stay on line and maintain speed. This level of stability is particularly beneficial for golfers who struggle with consistency under pressure.

SL 90 Stroke Lab Shaft

The Odyssey SL 90 Stroke Lab shaft is a purpose-built lightweight steel shaft engineered specifically for Square 2 Square putters. A counterbalance weight is integrated into the butt end of the shaft, working in concert with the Oversize grip to shift the balance point higher in the club and promote a more pendulum-like, arm-driven stroke. The reduced shaft weight allows the putter head to feel more connected and stable through impact, resulting in smoother tempo and a more repeatable putting motion. The shaft is precisely tailored to complement the center-shafted geometry of the MAX STRIPE head, ensuring the stroke-balanced properties of the design are fully realized. Available in 33", 34", and 35" lengths to suit a wide range of player heights and setup preferences.

Oversize Grip

The Oversize grip fitted as standard on the MAX STRIPE is specifically chosen to complement the stroke-balanced philosophy of the Square 2 Square line. Its larger diameter encourages a light, even grip pressure that keeps the hands passive and the larger muscle groups of the arms and shoulders in control of the stroke. This reduces the tendency for the wrists to break down or the forearms to rotate at impact, supporting the putter's natural square-face orientation. The grip's size and weight also contribute to the counterbalance effect created by the SL 90 shaft, keeping tempo smooth and consistent across a full range of putt distances.
