Optimize your set up with a Performance Kit! Inferno features a vibrant red-on-black color scheme and the distinct spiral pattern that our best-selling FPS Freek® Vortex™ made famous. The comfortable spiral pattern adapts to the pressure you put on it, so the harder you play, the harder Inferno works to keep your thumbs from slipping. Inferno’s 9.9 mm of added height increases the an arc distance by 135.5%. This gives you the ability to make smaller, more precise in-game movements, affording you the luxury of turning up controller sensitivities to maximum levels so you can turn on your opponents faster and gain the upper-hand. Performance Grips™ by KontrolFreek are advanced controller grips that utilize a combination of advanced materials that give gamers better grip, support and comfort. Grips utilize a moisture-wicking combination of advanced proprietary materials to achieve enhanced grip and comfort. The Inferno Kit includes Inferno Performance Thumbsticks and Inferno Red Performance Grips.
