This is so perfect for hardcore hiking. Should be a huge seller among Canadians as well as apocalyptic doomsayers looking to keep a technological edge.

I just love that @boredelonmusk is hunting stuff

Saw this product on Shark Tank. Cool concept for 3rd world countries

I'm a big fan of this thing.
