Tretorn Serie+ Tour 4pcs

Tretorn has developed a tennis ball with a multi-layer structure that makes the tennis ball hold the gas pressure even more. Pressurized tennis balls tend to lose pressure after a while, so now Tretorn has developed a new type of pressurized tennis ball to hold better thanks to the multi-layer construction.

The Serie+ Tour 4 Tube is a ball equipped with TRI-TEC™ technology for exceptionally long durability and high performance. The thin rubber core and high-quality European felt provide excellent feel and make the ball extremely responsive.

• TRI-TEC Membrane
• Thin core
• Top quality European woven felt.
