Otterbox is known for its durable cases that provide much more protection than your typical case. The company has expanded its portfolio by announcing that they have bought rival LifeProof. The purchase was announced at the CITA conference today. Terms of the deal remain confidential.

According to a press release from LifeProof:

“The joining of OtterBox and LifeProof is a way to combine two great brands and provide customers with even more great products, services and choices for smartphone accessories,” OtterBox CEO Brian Thomas said. “Both companies are successful because we foster an environment where everyone takes pride in being part of a culture that knows how to identify opportunities and grow them quickly. Our goal in this acquisition is to create more value for our customers than we ever could have generated while operating individually.”

Otterbox has been around since 1998, and has focused on making cases for a variety of gadgets, including phones and tablets. They claim to own 23% of the case market. This deal helps solidify its position as the leader in durable cases.
