Yonex adds another chapter to the EZONE 100SL! With its light weight, this racket makes it easier to address the ball with confidence. It packs enough pop to keep your opponents in check while giving you the needed spin potential to bring the ball down accurately. This racket's raw speed also shines at net where it comes around fast to deliver easy shot placement. For 2025, Yonex overhauls the frame's geometry, thickening the beam in the upper hoop to enhance power and stability while adding a groove on the inner portion of the frame to help the racket bend optimally through impact. To further enhance comfort, Yonex adds ultra-thin and flexible fibers to the shaft (called Minolon) to dampen harsh vibrations. Yonex also continues with 2G NAMD SPEED, an advanced material innovation that helps the frame transfer more energy to the ball. The most important design feature is the ISOMETRIC head shape, which gives this stick an undeniably more plush and responsive feel than conventionally shaped equivalents. With some nice tweaks to the feel and response, this update provides a very easy learning curve to those who are looking to play aggressive tennis.
