Diadem Solstice Power 16L Tennis String (12m Set) – Teal

The Diadem Solstice Power 16L is a spin-focused soft co-polyester tennis string designed to deliver exceptional ball bite, control and a more comfortable response than many traditional polyester strings.

Its distinctive six-pointed Star Core shape helps the string grip the ball at impact, while the low-friction surface encourages string movement and snapback. The result is excellent access to topspin while maintaining the controlled response aggressive players expect from a co-poly.

In the thinner 16L gauge (1.25mm) version, Solstice Power provides increased feel and spin potential, making it a great option for players who prioritise performance and ball connection over maximum durability.
