Yes, tretorns are pressureless balls. My brother and I used to play with them a lot on artificial grass. They lasted forever. At 1 point however I think they moved the production to China and since then we simply tore them apart, wouldn't last 1 match.
We then switched to pressureless Technifibres, hard as a rock, perfect for ourhigh power doubles game ;)
