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.”

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."

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.
