Designed for use with Tour Turf Mats

Simulate a deep, drop-in hole and use the large full-width shim to create a variety of different breaks and contours on your putting mat. Designed specifically to make the holes deep and easily create a "double depth" feel. These large shims can be used on one end of your putting mat, or on both ends to essentially give you a full 1" deep mat on each end where the holes are located. A game changer for feel and accurate practice. Engineered for use with the tour turf putting mats. 

Available in 4 different shapes depending on the type of break you would like to incorporate near the hole. Get a discount when you buy two!

When selecting your shim width, match the width of your Tour Grade Turf Putting Mat. 

The shim can be used on either the end with three holes, or the end with a single hole. Double Depth (1" deep) cups are also included.

*Looking for a full-width shim for a 2' wide or 1.5' wide mat? Available in the convex shape option here*

My Golf Spy

Best Outdoor Putting Green (2023) | “The roll and feel of the mat were highly praised, with many testers noting that it closely resembled the experience of putting on a real green. The durability of the mat was also commended, as it showed no signs of wear and tear even after extensive use.”

Sports Illustrated

Editor’s Choice for Best Putting Green (2024) | “Overall, the Birdie Ball Tour Grade Turf Putting Green provides a premium practice putting experience for golfers looking to improve their putting skills at home or in the office.

Golfer's Authority

"This is an outdoor/indoor hybrid that looks and plays like Augusta's practice green. Perfect if you want a backyard setup that doubles as indoor practice when the weather turns nasty."

Tour Grade Turf Built to Last

The highest quality artificial turf with ultra- thick backing combines durability with a premium, tour-grade roll.

THE BEST PUTTING TURF FOR A TRUE ROLL

Not all turf is created equal. We source the highest quality artificial turf tailored specifically to mimic a natural putting surface
MORE PREMIUM

HIGHEST QUALITY TURF

Not all turf is created equal, and ours is the best of the best. BirdieBall Tour Turf Mats have an ultra-tight weave and heavy face weight, combined with a thick and premium backing. This is the truest roll you can get on a turf surface. Grain Neutral with a 10-11 Stimp.

MORE REALISTIC

TURF WITH A TOUR ROLL

We use a premium synthetic turf to simulate a natural putting surface. The mix between a thick backing with an ultra-dense and short grass-like surface means your ball will stay on it's intended line and not fall into gaps in the turf surface. Competitors use a cheaper, less dense turf weave that causes the ball to constantly go off-line.

MORE PORTABLE

ROLLS UP FOR EASY STORAGE

Don't want to commit to a full backyard putting green install? BirdieBall turf putting mats roll up easily for storage and continue to lay flat for a perfect roll, every time.

MORE DURABLE

OUTDOOR OR INDOOR

Durable enough to be used outside and in the elements, but without sacrificing the premium tour roll. A perfect solution for outdoors or high traffic applications for a green that will hold up beautifully to weather, pets, etc.

BETTER ACCESSORIES

DROP-IN CUPS & EXTRACTION FLAGS

Thoughtfully designed so that the flag extracts the balls out of the hole for convenience.
This provides the best drop-in feel on the market. The putting turf is 1/2" thick, so the ball falls into the hole without needing an uphill ramp.
