Performance Grips by KontrolFreek are advanced controller grips that utilize a combination of advanced materials to give gamers better grip, support, and comfort. The grips are easy to apply and can be repositioned and removed without leaving a sticky residue. They utilize a moisture-wicking combination of advanced proprietary materials to achieve enhanced grip and comfort. The proprietary, honeycomb-stamped polymer outer layer maximizes grip while optimizing airflow to keep hands cool. The foam cushioning layer creates a feel much like dense memory foam, conforming to your palm and providing more support and comfort.
