The Tretorn Tennis Trainer Spare Ball is great to keep handy when you want to work on your swing with the Tretorn tennis trainer. Tretorn are the tennis ball experts and are a favourite brand for improving players that want premium quality when it comes to their sport. This spare tennis ball has a slower speed that’s ideal for junior players (aged 9 -10) and beginner adults sharpening their technique.With the pressureless construct you get just the right level of bounce (but not too much so you stay in control) and reliable performance no matter the weather conditions. Tretorn says this tennis ball is 20% lighter with 25% less bounce and speed than a standard ball and is teamed up with a softer feel.- Academy Stage 1 Tretorn Tennis Trainer spare ball- Mid-compression tennis ball- ITF approved
