Rubber and glass
Thick rubber sidewalls and Gorilla Glass help protect the screen and internal components. The XP 3300 is military-certified to withstand extreme heat and cold, dust, humidity, drops, and other environmental conditions.

Glove control
The keys look a tad small, but are ridged in the middle to help workers wearing gloves find and press the buttons.

Screw-tight
Screws keep the back cover and microSD card in place, while seals below the cover form a tight fit to keep components from shifting in rough 'n' tumble conditions.

Whoops
The phone is sturdy, not indestructible. Though 1.5 mm thick and able tot sustain drops up to 6.5 feet onto concrete, the strong Gorilla Glass screen didn't make it past our air-toss. The phone, however, still works, and there aren't any other scratches.
