Speck's Presidio Sport incorporates Microban anti-microbial technology and 360-degree protection for your phone case, even during your toughest workouts. Microban antimicrobial protection inhibits the growth of bacteria that causes stains and odors. Presidio Sport's IMPACTIUM Sport exterior provides a no-slip grip, even when your hands are sweaty. 360-degree port protection has port and button covers and a mute switch dial protect while keeping them accessible. Presidio SPORT cases have a grippy silicone exterior, a polycarbonate outer shell, and inner IMPACTIUM lining for three layers of protection in a one-piece case. Presidio SPORT is drop-tested to prevent damage from drops up to 12 feet with the IMPACTIUM Sport Shock Barrier. Ridges of IMPACTIUM Sport rubber inside the case compress on impact to absorb and disperse shock. All Speck cases are independently lab tested for multiple real-life situations to ensure your device is always protected. We test to protect against extreme drops, extreme temperatures, chemicals, antenna interference, cracks and abrasions, device bending, and more. This case comes with a lifetime limited warranty.
