Uni-Ball PowerTank RT SN-220 Ballpoint Pen, Black

This is the optimum outdoor pen for all sorts of weather conditions. If the McGuydude had had one of these, he would have conquered the whole world. This wonder pen even works at -20 degrees Celsius (-4 F), writes on wet paper, and in any position imaginable, including upside down or in zero gravity.

Features

All this did sound a bit too incredible, so we simply had to test it - and bloody hell, it works. We took it to the shower and it produced text despite the water. This uses stuff known as Super ink, which is oil-based, so it won’t turn into a Roschach test. It also worked in weird positions. The sub-zero conditions we haven’t yet tried but it should work there as well.

Thanks to the rubber grip, the pen is very comfortable to use. The tip is of course retractable, so you can hide it when you have nothing to write. The pen also has a pocket clip.

Use

Like previously mentioned, this is designed for tough outdoor use in all sorts of weather. So, it is perfect for military use, folks working at outdoor events, and everybody who needs to write something outside in rain and snow. It also works in cold storage facilities thanks to its cold-resistant ink
