If you need a laptop that can survive the elements, check out Panasonic's Toughbook 31, a refreshed version of the company's rugged laptop with a more powerful Intel processor, faster memory, and support for 4G LTE.

The Toughbook 31, which last got an update in 2015, now contains an Intel Core i5-7300 vPro processor and DDR4 RAM. In addition, the laptop can be configured with an LTE-Advanced module so you can browse the web wirelessly, without the need for a Wi-Fi hotspot.

However, this 13-inch Windows 10 laptop isn't cheap. It'll start at $3,699 when goes on sale next month; the base model comes with 16GB of RAM and a 256GB SSD. You can also configure the notebook with 32GB of RAM, and switch out the Intel i5 processor for a faster i7-7600U chip.

The Toughbook 31 is a bit hefty at 8.6 pounds—possibly 9 pounds if you add a second battery to the device.

Panasonic designed the Toughbook 31 for workers who traffic in extreme conditions, such as soldiers, police officers, or power utility employees. It can survive a beating thanks to the laptop's durable casing; in the video, you can see it being dragged through the dirt by an all-terrain vehicle.

You can now expect 19.5 hours of battery life on a single charge as opposed to 18, Panasonic says. If the second battery is added, that jumps to 29 hours. You can find a full spec sheet here.

The new Toughbook 31 will go on sale through Panasonic and its official resellers. Until then, check out our review of the laptop's sibling, a PC-tablet hybrid called the Toughbook 33.
