      Tretorn Micro-X Pressureless Bag of 72 Yellow and White 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.

      Balls have less bounce they my 1 year old bag of grey and yellow tretorns.

      I just bought these and at the last minute the company said I could take the all-yellows, which they had in stock, or I could wait for another month or so for the grey and white. Right away, I noticed, they don't have nearly the same pop as the grey and yellows I have had for about a year. I thought maybe after they wore in, it would change, but nope. Makes it tough to use them with my other Tretorns. The originals are still the best pressureless ball used to date by far.

      They Bound on Cold Weather

      Best pressureless tennis balls in the market. I mainly bought them for winter play, when regular tennis balls don't bounce, these do. All other pressureless tennis balls I have tried are heavy and hard. These feel very close to regular tennis balls.
