Zsig are at the forefront of creative coaching equipment & training aids for all racket sports encouraging the development of the next generation of sports stars. The Slocoach Big Red ball is a super-low paced ball with a slower & easier to control bounce. It's felt-covered, yet light enough to be used with mini tennis rackets, allowing children to ease out of sponge ball play without necessarily changing racket or court size. Ideal for use in service boxes up to three-quarters of a full size court & brilliant outdoors making it ideal for the next generation of Andy Murrays. Please note: We cannot guarantee the balls will be supplied in the carry-net as pictured.
