Tretorn Micro-X Pressureless Bag of 72 Yellow Tennis Balls

Tretorn's Micro X ball is approved by the USTA and performs like a tournament ball making it ideal for advanced players. It offers unsurpassed feel, playability and wear-resistance through micro cellular technology.

Micro X balls have a consistent bounce making them great for ball machines.

Technology

Micro Cellular Technology: Neither pressurized nor permanent pressure, Tretorn's micro cellular technology is patented worldwide and recognized by the ITF as the pioneer of a new category of tennis ball. The result is a highly playable tennis ball that does not lose performance over time.

A conventional pressurized ball flattens on the stringbed as it is hit and resistance is provided by the compressed air within the ball. A small amount of air escapes each time the ball is struck, reducing air pressure and performance. With this new category of ball, 700 million air-filled micro cells take the place of compressed air. These cells cannot escape through the ball's rubber core, resulting in a ball that never loses its bounce.

The rubber core, made of titanium and polybutadiene, has a softer feel than permanent pressure balls, enhancing spin. Surfaced with Tretorn's exclusive Flex-Felt, which is specially designed from wool and polyester fibers, the Micro X offers unsurpassed feel, playability ad wear-resistance.

Best practice balls ever

I have used Micro X balls for drills and a Playmate machine. They do not ever go dead. Eventually the ball machine balls lose their fuzz and still bounce years later.

Trecorn X tennis ball's work great

They are the best for a ball machine. I've been using them for years. They beat out Penn by far in terms of how well they resemble a real tennis ball when hitting them and they are long lasting too.

Holabird shipped them out quickly and I was loading them into the hopper in no time.

Quick Response with Quality Products

I often use the ball machine when teaching beginner to intermediate athletes. Having tested many brands, like other teachers/coaches, I found that the Tretorn MicroX pressure-less ball holds up longer than almost any other. It maintains good bounce and the felt holds up quite nicely (longer lasting). A couple negatives: they cost more than most balls and the supply is often low. The weight and performance is close enough to your standard competition tennis ball for teaching purposes.

Holabird Sports is quick to respond with any product. I highly recommend them for your tennis needs.

reliable, long-lasting and consistent

Despite the high cost, these balls are the best for use with a ball machine. I first used Tretorn balls when learning to play as a child 60 years ago, and used a single box for one entire Summer. The current balls continue the legacy of quality.
