Performance Grips by KontrolFreek are advanced controller grips that utilize a combination of advanced materials that give gamers better grip, support and comfort. Grips are easy to apply and can be repositioned and removed without damaging your controller. Grips utilize a moisture-wicking combination of advanced proprietary materials to achieve enhanced grip and comfort. Our 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 the harder you game. Grips are latex, PVC and VOC free. Grips can be applied multiple times and repositioned easily without damaging your controller.
