Tough Xtreme is Case-Mate’s most rugged Samsung Galaxy S4 case, delivering our highest level of protection in the thinnest possible construction. It combines military-grade protection with a sleek, non-bulky style. The extremely durable design is formed from three layers of toughness. A soft exterior wrapped around a hard skeletal structure is fused with a soft, impact-absorbing interior. The built-in screen protector prevents screen scratches and cracking.
