The S31, by Cat, is made impervious to dust and water by its rather hulking IP68-grade shell, while it matches its sturdy exterior with a substantial 4000mAh battery sitting in the engine room. To wrap it up, it withstands drops from up to 1.8 meters through its MIL-SPEC 810G military standard certification.

Also known as: Cat S-31.
