Spigen Rugged Armor
Spigen is one of the most popular case manufacturers. They offer a few different designs that are thin, some are thick, and others have kickstands. Spigen is one of the first brands I turn to for protection.
The Rugged Armor is one of the best. It isn't too thick, not too thin, and has a durable polycarbonate plastic body. Then up top where the Pixel glass is, they've added a carbon fiber design for additional style. It has glossy accents and reinforced corners for total protection.
