Only the fittest phones survive | OtterBox

Legendary OtterBox drop protection.

Only the fittest survive

Before they ever get the chance to touch your phone’s display, our phone screen protector designs pass punishing tests in our lab. We go to new heights to keep your screen safe, conducting controlled, flat face drops to simulate the rough-and-tumble world outside. Premium Pro Glass and Premium Glass protect your device screen from cracks and chips.

Only the screen protectors that have survived scratches and triumphed over tumbles get the DROP+ designation — all so you can be sure your screen is in safe hands.

Passion for phone protection | OtterBox

Passion for protection

DROP+ is a promise that every product we make is ready for whatever life throws at it — and that your device is protected so you can stay connected to the people, places and moments that matter most.

We test OtterBox phone cases for everything you can think of. And a lot of things you probably wouldn’t even imagine. Each OtterBox case series must pass every test before it’s certified DROP+.

What is Military Standard?

Military Standard (MIL-STD)* is a series of tests designed by the US Department of Defense to determine the overall durability of a product.

It requires a case and device be dropped 26 times from 4 feet. This proves the edges, corners, front and back of a case prevail through multiple impacts, and that we’ve made the toughest military grade phone case possible.

*MIL-STD-810G 516.6

MIL-STD Meets the OtterBox Standard

We take our testing even further and subject our cases to MIL-STD testing multiple times.

1X, 2X, 3X, 4X, 5X — we fatigue test our cases again and again to ensure they survive drop after drop, not just the first few.

- 1X = 26 individual drops
- 2X = 52 individual drops
- 3X = 78 individual drops
- 4X = 104 individual drops
- 5X = 130 individual drops

Protection is in our DNA

24+ tests

The + in DROP+ represents the extra tests our engineers perform in addition to MIL-STD to deliver the most protective phone cases.

Top-secret tests are performed in the OtterBox Prototype Innovate Test (P.I.T.) Lab to make sure your device is protected from the unexpected.
