When you watch Jon Rahm hit a golf ball, whether it’s a towering drive that splits the fairway or a delicate chip that checks the pin, you’re seeing a master at work. He combines immense power with incredible touch, and a key part of managing that talent is using equipment he trusts completely. A critical piece of that puzzle is his golf ball: the Callaway Chrome Soft X. In this article, we’ll break down exactly what that ball is, why a powerhouse like Rahm relies on it, and how you can use the same logic to determine if it’s the right ball for your game.

The Simple Answer: Callaway Chrome Soft X
Jon Rahm plays the Callaway Chrome Soft X golf ball. This has been his ball of choice since he signed his major equipment deal with Callaway in early 2021.
Before making the switch, Rahm was a long-time Titleist Pro V1x player, which gives you immediate insight into the type of performance he demands. Both the Pro V1x and the Chrome Soft X are premium, multi-layer golf balls designed for high-swing-speed players who want low spin off the driver and high spin around the greens. When Rahm moved to Callaway, he went through a rigorous testing process to find the model that best replicated - and even improved upon - the performance characteristics he had relied on for his entire professional career.

Why Does Jon Rahm Use the Chrome Soft X? A Performance Breakdown
A player of Rahm's caliber doesn't choose a golf ball based on sponsorship alone. The performance has to be there, and it has to fit his specific needs. The Chrome Soft X is an engineering marvel designed for the best players in the world, and its features align perfectly with Rahm's aggressive, powerful style of play.
The Hyper Elastic SoftFast Core
At the center of the Chrome Soft X is its engine: the Hyper Elastic SoftFast Core. This is not just a uniform piece of rubber, it’s a sophisticated core designed to act differently depending on the impact.
On high-speed shots (like a driver): When Rahm unleashes his driver, the core is resilient and provides a high-speed launch with low spin. This is the recipe for distance. The low spin helps the ball pierce through the air without ballooning, maximizing roll and total distance - a massive benefit for a long hitter.
On lower-speed shots (like a wedge): On touchy shots around the green, the "SoftFast" part of the name comes into play. The core feels softer, which allows the ball to stay on the clubface just a fraction longer. This, combined with the urethane cover, generates the high spin needed to check the ball on command.
For Rahm, this dual-personality core is essential. It allows him to have the 'best of both worlds' - the explosive, low-spin distance he needs off the tee and the delicate, high-spin control he uses to attack flags with his irons and wedges.
Tour Aero Design for a Penetrating Flight
Take a close look at a Callaway ball, and you'll notice the dimples aren't perfectly round, they're hexagonal. This is Callaway’s signature Tour Aero design. These carefully mapped hexagons are engineered to reduce drag while maintaining a high lift, creating a ball flight that is both powerful and stable.
For a player like Rahm, who generates immense ball speed, this is critical. A less aerodynamic ball would climb too high and get tossed around by the wind. The Chrome Soft X produces a strong, more penetrating trajectory that holds its line, especially in the breezy conditions often found at major championships. His reputation as one of the world's best wind players is certainly helped by a ball that refuses to get knocked off course.
High-Performance Urethane Cover for Greenside Control
The "X" in Chrome Soft X signifies that this is the firmer, higher-spinning model in the lineup. A huge reason for this spin is its soft-but-durable thermoset urethane cover. Urethane is the standard material for premium, Tour-level golf balls for one reason: short game spin.
When you hit an approach shot with an iron, the grooves "bite" into the soft urethane cover, creating maximum friction and spin. This is what allows Rahm to hit those towering irons that land softly and stop quickly. Around the greens, it allows for all the "action" a player could want - a crisp chip that takes one hop and stops, or a pitch shot that checks up right next to the hole. A harder, non-urethane cover (like Surlyn, found in most distance balls) simply can’t generate this level of greenside control. This spin gives Rahm the confidence to fire at any pin, knowing his ball has the stopping power to hold the green.

This is where we transition from understanding Jon Rahm’s game to improving your own. Simply put, just because the Callaway Chrome Soft X is an incredible piece of technology for one of the world's best, it doesn't automatically mean it's the optimal choice for you. Here’s how to decide, thinking like a coach.
1. What Is Your Swing Speed?
This is the most important factor. The Chrome Soft X has a higher compression rating (around 95) compared to the standard Chrome Soft (around 75). Compression is essentially a measure of how "firm" or "soft" a ball is. Higher compression balls require more clubhead speed to compress fully at impact.
If your driver swing speed is 105 mph or higher: You have the necessary speed to properly activate the core of the Chrome Soft X. You will likely benefit from its low-spin characteristics off the tee and feel its responsive performance on all your shots.
If your driver swing speed is below 105 mph: You'll likely struggle to compress the Chrome Soft X. At slower speeds, a high-compression ball can feel hard, like hitting a rock, and you may actually lose distance because the core isn't being fully engaged. Players in this category would almost certainly benefit more from the standard Callaway Chrome Soft or another lower-compression tour-quality ball. It will feel better, launch higher, and likely give you more distance.
2. What Feel and Spin Do You Prefer?
Let's forget swing speed for a moment. How do you want the ball to feel and react?
The Chrome Soft X is designed to feel "softly firm." It provides audible feedback and a solid feel off the longer clubs but retains that soft, buttery feel around the greens. However, feel is subjective. Some players love a ball that feels almost mushy off the putter face, while others prefer a firm, "clicky" ball that gives them more audible feedback.
More importantly, do you need the spin of the X model? Top pros need maximum spin to stop the ball on the firm, fast greens found on the PGA Tour. Many amateur courses have softer, more receptive greens. Many amateurs would benefit from less spin on their iron shots to reduce side-spin from hooks and slices. For these players, a ball like the standard Chrome Soft, which spins a bit less with the irons, might actually lead to straighter shots and more greens in regulation.

Choosing the right ball is one of the easiest ways to improve your scores without changing your swing. Follow this simple, pro-level process to find the one for you.
Step 1: Start on the Green
Everyone wants more distance, so they test balls on the driver. This is backward. You hit your driver about 14 times a round but use your wedge and putter 40+ times. Start with the scoring clubs. Get a few sleeves of balls you're interested in (e.g., Chrome Soft X, Chrome Soft, Pro V1) and head to the practice green. Hit chips and putts. Which one feels the best? Which one produces the flight you like on little chip shots?
Step 2: Move to the Fairway
Once you’ve narrowed it down to two or three based on short-game feel, take them to a practice fairway or an open spot on the course. Hit 7-iron shots. Watch the ball flight. Do you want it higher or more penetrating? Does it stop how you'd like? This will show you how the ball performs with your irons.
Step 3: Finish at the Tee Box
Finally, hit the few contenders with your driver. At this point, you're not just looking for the absolute longest ball. You already know they all feel good and perform well on and around the green. Now you just need to confirm which one gives you a great combination of distance and a tight dispersion.
Step 4: Commit to One Ball
Once you’ve found a ball that checks all the boxes, stick with it! Playing a different brand or model every round is a recipe for inconsistency. You cannot develop a feel for distance control with your putter or predictability with your wedges if the tool you are using is always changing.
Final Thoughts
Jon Rahm plays the Callaway Chrome Soft X for a reason: its combination of low-spin distance and high-spin control is engineered perfectly for his elite-level power and precision. For amateur golfers, the key takeaway is not to simply copy him, but to copy his process of matching equipment to your unique game - specifically your swing speed, feel preference, and performance needs.
Ultimately, making informed decisions is at the heart of playing better golf. Knowing you have the right ball in play is a huge confidence booster, but that's just one piece of the puzzle you face on every shot. For all the other decisions, like club selection, on-course strategy, or navigating tough lies, you should know that help is available.
