Matias has been playing with ReString Zero since January 2023. Although now retired from professional and collegiate tennis, he was once one of the highest ranked juniors in Argentina playing alongside Diego Schwartzman and Andrea Collarini. As a Collegiate athlete, he was a 1st team All-American for Georgia State going 9-1 in his final season for singles and finishing N6 by the ITA ranking. He has since continued to maintain his high level as a hitting partner for ATP and WTA players Horacio Zeballos, Juan Ignacio Londero and Lourdes Carle. Here's what he had to say about ReString Zero:
"I love the way Zero feels in my racket, particularly with how much power it provides. The String feels softer than what I'm used to but I had no problems swinging fully with no fear of over-hitting. The durability of play is really great. Zero feels fresh even after hours of hitting across a few weeks. Even after the tension settles in a bit, the grip on the ball stays solid! Very impressed with the spin generation on this one!"
