Our Mission
Athletes Shouldn't Have to Choose Between Performance and Longevity.
Every RTP product starts with a single question: what does the court actually cost your body? We partner with biomechanics researchers and materials scientists to engineer performance gear that protects as hard as you play.
The Complete Court Protection System
WHY RTP EXISTS
A coach built this because he lost two years to injury and couldn't find gear that worked.
Sky Kim had his tennis career derailed twice by injury. He went on to coach at the highest level of the ATP tour — helping Hyeon Chung defeat Novak Djokovic at the 2018 Australian Open. He built RTP because he could not find gear engineered to prevent the injuries he had lived through.
The Technology
Sorbothane®
Standard dampeners change the sound of impact, they don't change the physics. Your muscle doesn't care what it sounds like, it responds to low-frequency vibration at 25–500 Hz. Sorbothane is the only material that absorbs specifically those frequencies.
