Diadem Sports was founded in 2015 in South Florida with a single focus: set the standard for performance equipment in racket sports. It started in a garage with one tennis string and spent years working to get it right.

Solstice Power is a comfortably soft co-poly with a six-pointed star shape — a low-friction surface with maximum ball bite. Diadem says it was built for spin.
